Enterprise resource planning
Enterprise resource planning 1. INTRODUCTION Enterprise Resource Planning (ERP) systems are among the most important business information technologies to emerge in the last decade. The basic concept of Enterprise Systems is focused mainly on standardization, synchronization and improved efficiency. Thousands of major construction firms and increasing numbers from other sectors as well, either have just completed their first ERP implementations or are in the middle of this major undertaking. ERP systems can be defined as configurable information systems packages which integrate information and process across organisational functional areas (Kumar and Hillegersberg, 2000). The benefits of Enterprise Systems are very significant: coordinating processes and information, reducing carrying costs, decreasing cycle time and improving responsiveness to customer needs (Davenport 2000). Keeping the project on schedule, under budget and the quality are usually are the main problem that has been faced by the construction industry. Construction industry is one of the major industries in contributing the economy, eventhough it is measured to be one of the most highly fragemented, inefficient and geographically detached industries in the world (Chung, 2007). To overcome this inefficiency, a number of solutions have long been offered including implementation of IT. In the context of the construction industry, ERP would be defined as a computer-based business management system that integrates all processes and data of the business, including engineering/design, planning, procurement, construction and maintenance/operations (Tatari et al. 2007). Now a days numbers of major construction companies are implementing the integrated IT solutions such as ERP systems to better integrate their various functions. However, these integrated systems in construction present a set of unique challenges, different from those in the manufacturing or other service sector industries. Each construction project is characterized by a unique set of site conditions, a unique performance team, and the temporary nature of the relationships between project participants. This means a construction business organization needs extensive customization of pre-integrated business applications from ERP vendors. Unfortunately, such an extensive customization can lead a construction firm to ERP implementation failure. The ERP applications that are used by construction industry can be classified into two distinct groups: pre-packaged Software, and Web-based Project Management System (WPMS). Currently, the worlds biggest pre-packaged ERP software contributors involve SAP, Oracle, PeopleSoft, J.D. Edwards, and Baan. SAP is said to have about 60% of the world market (Holland, Light, Kawalek, 1999). 2. Problem Statement ERP has become an essential part of enterprise method over the globe. Use of ERP in other sectors is being stable and growing. Its critical influence within designing novel business environments and procedures has been noteworthy. Different organizations in assorted subdivisions have dedicated to paying out and have already paid out large summations of capital for the implementation of ERP in their organizations. These equivalent companies possess been able towards document major improvements, both concrete and elusive, within their campaigns as a outcome of ERP implementation. Large number of organizations have implemented ERP in their process and make it more effective and profitable. The same observation can be made for some of the most successful corporations in the world. The question needs towards be asked why is this? What are a number of the listened benefits that inflict corporations devote towards the implementation of ERP within their organizations? According to Oliver, Romm (2002), in common with other types of investment activity the adoption of an ERP system is a purposive intervention by an organization for bringing about a new state of affairs that is judged to be superior to the current state. The most bulk valued factor that are often stated as a intent for performing to the implementation of ERP: Integration Access of Information Improvement in process Thoughtfulness in business Dissatisfaction with out dated legacy systems After implementing ERP companies have been competent to enhance costumer relation, strengthen delivering the flexible supply chain partnerships, improving the organizational flexibility, improve decision-making competency and decreasing task culmination time and cost (Ahmed, and Ahmed, Azhar, Mallikarjuna, 2003). Although Enterprise Resource Planning (ERP) has been completely applied by various associations internationally, within almost everybody of the else principal industrial sectors, its utilization in the building industry has been limited to exert via a few large organizations The greatest gatherings of construction administration that have either failed in their efforts to take on this technology, or are not very apparent with it are Small and Mid Size Construction Organizations. These organizations comprises the strength of the construction industry and have their possess specified commercial and operational needs. The failure of Small and Mid Size Construction Organizations to adopt ERP, despite all its promise advantages, is a problem that desires to be addressed. It can be proposed that 2. RESEARCH PURPOSE The overall purpose of this research is to assess the critical success factors for the implementation of ERP systems to support construction industry and to what extent it is being used in enterprise integration and the benefits derived from using ERP systems. Furthermore, success factors coupled with the organizational performance will be assessed and validated. The relationship between the perceived performances will be assessed against the influence of upper management support, role of project champion in managing change in the organization, the level of organizational emphasis on communication and training, and organizational experience with ERP systems. 3. RESEARCH AIM The proposed research endeavours to investigate the following questions: What issues and problems faced by Construction organisations during the implementation of ERP systems? How can problems be reduced in implementing complex new technology into the existing structure of an organization? What must be considered, from the organizational as well as the technical perspective, to effectively integrate the technology and people in the organization who use it? Although this study cannot fully answer these questions, this research will provide valuable information concerning the technological and management systems used to support Construction organizations. Evaluation of implementation and problem issues will serve to further support management decision making. 4. RESEARCH QUESTIONS This research will identify the characteristics of ERP systems used in todays Construction industry. The results of this research will provide additional realistic information for construction organizations seeking to implement ERP systems, providing recommendations pertaining to the issues that must be addressed for companies to avoid critical problems in their own implementation of ERP systems. Questions to address: What are the critical success factors for implementing ERP system in a Construction organization? Is upper management support crucial to the success of ERP systems? What are the change management strategies the management should employed to help the successful implementation and performance of ERP systems? Is the success of ERP system depends upon the level of effective communication and the employee education and training? The generalized question to which this research will contribute is: What are the basic factors that determine the success of ERP systems implementation in regards to the ability of the system to influence organizational performance? When an organization decides to implement and integrate an extended, inter-departmental computer system into its operations, what issues must be addressed to indemnify that the computer application system will effectively contribute to organizational performance improvement? 5. RESEARCH OBJECTIVES The objectives of this research are as follows: To independently obtain current information regarding the state of ERP systems in Construction organization today. To determine the critical success factors for implementing an ERP system in Construction organisation. To survey current users about factors that contribute to the success of ERP systems, especially in regards to effective communication, user training techniques, change management and the effect of upper management support. This will serve to validate previous research as well as obtain more information about successful experiences in industry. 6. Research method The research method appropriate for this research project will be of qualitative nature through an interpretive case study, where data collection techniques will consist of thorough literature review, secondary data review of documentation regarding the ERP project and interviews from senior computer, technical and management consultants. 2. Literarture Review 1. INTRODUCTION Literature is a term that refers to all sources of published data and Literature Review is a written summary about the findings from the literature (Hussey and Hussey, 1997). A literature review helps in establishing what research has been conducted on the researchers chosen area of study and also to identify what research is currently in progress (Saunders et al., 2000). In order to research into Enterprise Resource Planning (ERP) systems, a thorough literature review has been conducted with a centre of attention placed on ERP systems and the implementation of these systems in Construction organizations. Previous papers on ERP implementation projects will be reviewed focusing on successes and previous failures in ERP projects. As the research site is Hindustan Construction Company Ltd., the coonstruction sector has also been reviewed. 2. ENTERPRISE RESOURCE PLANNING 2.1The ERP Phenomena ERP systems are highly integrated software packages (Holland et al., 1999) that can be customised to cater for the specific needs of an organisation (Boudreau and Robey, 2000; Esteves and Pastor, 2001; Laberis, 1999). The concepts that have been evaluated and, at times, utilized by construction organizations in achieving the goal of improved efficiency through better management of collaborated knowledge is Enterprise Resource Planning (ERP)(Negahban and Baecher 2008). ERP systems have been defined to be a computer program that provides a general working platform for all departments of an enterprise with their management functions being integrated into the program (Jingsheng Halpin, 2003). Several definitions from the published literature are given to further explain the concept: ERP (enterprise resource planning systems) comprises of a commercial software package that promises the seamless integration of all the information flowing through the company-financial, accounting, human resources, supply chain and customer information (Davenport, 1998). ERP systems are configurable information systems packages that integrate information and information-based processes within and across functional areas in an organization (Kumar and Van Hillsgersberg, 2000). One database, one application and a unified interface across the entire enterprise (Tadjer, 1998). ERP systems are computer-based systems designed to process an organizations transactions and facilitate integrated and real-time planning, production, and customer response (OLeary, 2001). Kapp et al. (2001) defined ERP as a system of integrated procedure, rules and algorithms designed to function consistently time and time again (p. 85). The key point in an ERP system is integration. The purpose of ERP is to create one computer system that can perform all the functions of every department within an organization by linking all the departments into one single database. What ERP really does is organize, codify, and standardize an enterprises business processes and data. According to Negahban, S, 2008 By utilizing this technology would allow the construction industry to harness the power of collective knowledge. In addition, regulatory and competitive forces, financial demands of owners, and an ever-shortening timeline to finish projects contributed to an increased pace of the utilization of this technology in the construction industry. It took the construction industry longer than other industries to realize the importance of the utilization of IT applications in improving the possibility of ultimate success in an integrated project environment. 2.2 Evolution of ERP The history of ERP can be traced back in 1960s, when the system focuses mainly towards inventory control (Seo, 1999). During 1970s, a shift of focus towards MRP (Material Requirement Planning) was observed. This system helped in translating the master production schedule into requirements for individual units like sub assemblies, components and other raw material planning and procurement. This system was involved mainly in planning the raw material requirements (Kalakota and Robinson, 2001). Then, in 1980s came the concept of MRP-II (Manufacturing Resource Planning) which involved optimizing the entire plant production process (Seo, 1999; Kalakota and Robinson, 2001). In the beginning, MRP-II was an extension of MRP to include shop floor and distribution management activities. Afterwards, it was further extended to include areas like Finance, Human Resource, Engineering, Project Management etc (Seo, 1999). This gave birth to ERP (Enterprise Resource Planning) which covered the cross-functional coordination and integration in support of the production process (Seo, 1999; Kalakota and Robinson, 2001). The role of enterprise resource planning (ERP) does not match its name. It is no longer related to planning and resources, but is rather related to the enterprise aspect of the name. ERP attempts to unify all systems of departments together into a single, integrated software program based on a single database so that various departments can more easily share information and communicate with each other.(chung,2007).The ERP include the entire range of a companys activities. It addresses both system requirements and technology aspects including client/server distributed architecture, RDBMS, object oriented programming etc (Bancroft, 1996). ERP systems are designed as an integrated set of software modules, all linked to a common database, handling a host of corporate functions such as finance, human resources, material management, sales etc. (Slater, 1998). Russell and Taylor (1995) suggested that the ERP of today differ from traditional MRP II system in the areas of relational database management, graphical user interface (GUI), fourth generation languages (4GL), client-server architecture and open system capabilities. In addition, Kapp et al. (2001), stated that the differences between ERP and MRP II is the inclusion of a variety of manufacturing processes within ERP, in which modern ERP software is able to handle both discrete work orders and flow orders, JIT and MRP, EDI, and hand-entered orders (p. 86). Wainewright (2002) also stated that MRP was used for tracking suppliers, work-in progress and the output of finished goods, while ERP was used for all type of business with additional functions including financials, payroll and human resources management. Furthermore, Kremzar and Wallace (2001) also stated that ERP is far better than MRP II for three reasons: a) ERP applies a single set of resource planning tools across the entire e nterprise, b) ERP provides real-time integration of sales, operating, and financial data, and c) ERP connects resource planning approaches to the extended supply chain of customers and suppliers. According to Koch(2002) the main reasons that companies take ERP are summarize below: Because of its Integrated Financial Information i.e. to create a single version of information which cannot be questioned because all the members of the company use the same system. The information is integrated on one system rather than scattered on many different systems that cannot communicate which each other, so that the company can track orders and can coordinate with different related departments across many different location at the same time. It standarized and speed up the process using single integated system which can save time and increase productivity. Reduces inventory by improving the observation ability of the order process inside the company. The popularity of ERP systems started to soar in 1994 when SAP, a German based company, released its next generation software known as R/3 (SAP, 2003). In the following years, companies began to pour billions into ERP systems offered by SAP and its major competitors such as Oracle, Baan, J.D. Edwards, etc. Recently, ERP vendors add more modules and functions as add-ons to the core modules giving birth to the new term i.e. extended ERPs or ERP II (Adam and Sammon, 2004). It is the enterprise systems for the 21st century. These ERP extensions include advanced planning and scheduling (APS), e-business solutions such as customer relationship management (CRM) and supply chain management (SCM) (Bhattacherjee, 2000). ERP II systems are about optimizing the supply chain through collaboration with trading partners. It crosses all sectors and segments of business, including service industries, government, and asset-based industries like mining (Turban et al. 2001). According to Zrimsek (2003), ERP II systems is web-based, open to integrate and interoperate with other systems, and built around modules or components that allow users to choose just the functionality they need. Figure 1 summarizes the historical events related with ERP. 2.3 ERP Functions, Purpose of ERP Systems Enterprise Resource Planning (ERP) systems are software driven business management system which integrates all facets of the business, including manufacturing, planning, sales and distribution, financials and human resources (Kuang et al., 2001). It is a system that integrates all information that runs through an organisation (Davenport, 1998) and can be categorised as a large information system. It can be customised to cater the needs of an organization (Watson and Schneider, 1999). During 1990s ERP systems became the de-facto standard for replacement of legacy systems in large, and particularly multi-national companies (Parr and Shanks, 2000) ERP systems become more widely implemented, software applications are developed to help business managers implement ERP in diverse business activities such as project planning and management, subcontracting, material tracking, service, finance and human resources (tatari,2009) However, enterprise systems expanded to include back office functions (such as operations, logistics, finance, and human resources) and non transaction-based systems (Davenport, 1998) or front-office functions (such as sales, marketing, and customer service), as integral components of ERP systems (Davenport, 1998; Chen, 2001). This expansion result from the emergence of Supply Chain Optimization (SCO) (Chen, 2001), or Supply Chain Management (SCM) (Turban et al., 2001) and CRM strategies and systems (Chen, 2001), as illustrated in Figure 2. Turban et al. (2001) referred to this beyond the corporate walls integration as extreme integration (p. 304). Turban et al. (2001) further commented that in this approach to integration, SCM can be viewed as the brain and ERP as the strong body (p. 305). While the names and numbers of modules in an ERP system provided by various software vendors may differ, a typical system integrates all these functions by allowing its modules to share and transfer information freely and centralizing all information in a single database accessible by all modules (Chen, 2001). Provided in Figure 3 is an overview of an ERP system. Due to the importance of these systems in terms of added functionality over legacy systems and potential integration benefits, a large number of organisations are adopting these systems to manage their operations (Ross, 1999). They adopt these systems due to various technical or business reasons. Technical reasons include Y2K issues (myth), replacing legacy system that did not work etc. Organisations that have successfully implemented ERP systems view them as one of the most important innovations that have lead to the realization of substantial tangible and intangible improvements in a variety of areas (Davenport, 2000). Five other reasons for acquiring an ERP system are: 1) to integrate financial information, 2) to integrate customer order information, 3) to standardize and speed up manufacturing processes, 4) to reduce inventory level, and 5) to standardize Human Resource information (Koch, 2002). According to Kremzar and Wallace (2001), operating the business in a rapidly changing and highly competitive environment is the primary purpose of implementing an ERP system. Various studies have been done focussing on adoption and implementation of software applications (Harrison et al., 1997; Lassila and Brancheau 1999). However, the enterprise-wide implications, high resource commitment, high potential business benefits and risks associated with ERP systems make their implementation a much more complex exercise in innovation and change management than any other software package (Nelson and Somers, 2001; Gefen, 2000). Radding (1999) argued that when an organisation puts millions of dollars into a core business application and reengineers its business processes around it, the system is destined to become much more than an application. 2.4 General Perspective of Todays ERP Systems For over a decade the ERP system has had major impact on the manufacturing industry. Besides manufacturing companies, the ERP system has also gone further to serve the other industries. According to Boyle (2000), the ERP system is also linked with the web and e- commerce applications and beginning to use web browsers as the graphical user interface. Management was not using ERP to its full potential. Today, ERP is the foundation of businesses domestically and globally (White et al., 1999). It is used as a management tool and gives organizations a great competitive advantage (Koch, 2002). As ERP systems become more widely implemented, software applications are developed to help business managers implement ERP in diverse business activities such as project planning and management, subcontracting, material tracking, service, finance and human resources.(tatari,2009) Most of the ERP packages, today, provide multiple language and currency capabilities, allowing operations in different countries to become more integrated (Computerworld, 1998). In an era of globalization, such characteristics are very appealing for organizations desiring to expand their activities worldwide without losing control over them. The popularity of ERP is evidenced in a study that showed that nearly 19 percent of organizations across all industry sectors have installed ERP software (Computer Economics, 1999). The study also showed that the popularity of ERP continues to rise, with 34 percent of the surveyed organizations investigating, piloting, or implementing ERP packages. Davenport (1998) characterized ERP as the most important development in the corporate use of information technology in the 1990s (p. 122). 2.5 ERP Systems and Construction Organizations In the construction industry, because of the fragmented nature of the business, ERP implementation and utilization has not reached the same level as the other industrial sectors; however, the construction industry has finally awakened to importance of ERP, even though it is lagging behind other major industries that have been utilizing ERP to improve their efficiencies and bottom lines. (negahban,2008) There has been a remarkable improvement in both the speed and ability to conform to logical, customer-oriented business processes with the configurable and more flexible ERP systems (Donovan, 1998). In fact, now days, the management can chose from number of ERP products that come with multiple best practice options. The old MRP systems were very rigid as predefined business processes were embedded in the software making it difficult to adapt to the real needs of a manufacturing business (Seo, 1999). Customizing an off-the-shelf MRP system was expensive, difficult, risky and unusually time-consuming. As a result, companies had to make their order fulfilment process in such a way so as to accommodate the vendors predefined MRP software process but it greatly limits the managements ability to adjust their order fulfilment process to cope with changing customer requirements and to create a competitive advantage (Donovan, 1998). With todays developments in ERP software technology, compani es have an opportunity not only to configure business processes at much more reasonable cost and risk but also to create the opportunity for a competitive advantage (Kalakota and Robinson, 2001). The success of ERP in manufacturing enterprises resulted in its adoption by some large construction companies (ML Payton Consultants 2002; Voordijk et al. 2003). The high expectation of achieving all-round cost savings and service improvements is very much dependent on how good the chosen ERP system fits to the organizational functionalities and how well the tailoring and configuration process of the system matched with the business culture, strategy and structure of the organization. By implementing right ERP system, the organization significantly improve its entire order-to-delivery process, increase its ability to service customers at a lower cost and also better forecast its sales and other business activities, which is a competitive advantage (Harvard Business School, 1997). With ERP, it is possible to share and exchange information in digital format throughout the project life cycle. Thus, information is stored only once and all project participants are able to access this information in real-time(tatari,2009) Generally an ERP system is expected to improve both backbone and front-end functions simultaneously. Organizations decide to install ERP systems for many tangible and intangible benefits and strategic reasons. In various cases the calculation of return on investment (ROI) is weighted against the many intangible and strategic benefits (Gefen, 2000). However, to get the benefits of ERP systems, organizations need to undertake some problems and disadvantages. The advantages and disadvantages that organizations face after implementing ERP are given below: Benefits of ERP systems Integrating the organizations activities by processing a large majority of an organizations transactions (OLeary, 2001) and managing the information needs of companies (Gefen, 2000; Baskerville et al., 2000). Facilitation of intra-organization communication and collaboration (OLeary, 2001). ERP does the integrating job, allowing the business to spend less time figuring out whats going on and more time for improving (Slater, 1999). Options exist to purchase only the modules needed presently and acquire any extra modules needed in the future (Gefen, 2000). ERPs use an enterprise-wide database which allows access to the data in real time (OLeary, 2001). Both small and large companies can benefit both technically and strategically from investments in enterprise systems (Markus and Tanis, 2000) as they enable organizational standardization, eliminate information asymmetries and provide on-line and real-time information (OLeary, 2001). Disadvantages of ERP systems ERPs can have a negative impact on the work practices and culture of an organization (Allen and Kern, 2001; Soh et al., 2000). It takes an average of 8 months after the new system is installed to see any benefits (Koch et al., 1999). Lack of feature-function fit between the companys needs and the packages available (Markus and Tanis, 2000). The need for competent consulting staff to extensively customize the ERP (Gefen, 2000) to increase the acceptance of a new system. There is a need for extensive technical support prior to its actual use (Gefen, 2000). 2.6 ERP Systems Architecture ERP vendors understood the limitations of the old legacy information systems, i.e. MRP/MRPII systems, used in large enterprises of the 1970s and 1980s. Some of these old systems were developed in-house while others were developed by different vendors using several different languages, database management systems and packages, creating number of incompatible solutions unfit for the data flow between them (Seo, 1999). It was not easy to enhance the capacity of such systems or the users were unable to upgrade them with the organizations business changes, strategic goals and new information technologies (Chen, 2001). ERP systems are recognized for their databases and interdepartmental linkages. ERP structure provides a basis for MRP systems to become an enterprise integration tool (Kalakota and Robinson, 2001). Enterprise integration is viewed as developing the availability and accessibility of information within an extended corporate system and using the information system to efficientl y coordinate both the decisions and actions of thousands of individuals (Enterprise Integration Laboratory, Univ. of Toronto, 1994). To operate in an enterprise sense, the organizations need to distribute their applications for costing, planning, scheduling etc to accommodate the multiple layers of the organization, its work centers, sites, divisions and management levels (Turban et al., 2001). Multiple languages and currencies are also being included for global applications (Chase and Aquilano, 1995). The characteristics of an ERP system are as follows: Modular design containing many distinct business modules such as financial, manufacturing, accounting, distribution, etc (Davenport, 1998; Chen, 2001). Use centralized common database management system (DBMS). It is based on distributed, client/server computer systems (Wood and Caldas, 2001, p. 387). The modules are integrated and provide seamless data flow, increasing operational transparency through standard interfaces (Holland et al., 1999). It is generally complex system involving high cost (Davenport, 1998). It is flexible and offer best business practices (Davenport, 2000). It requires time-consuming tailoring and configuration setups to integrate with the business functions of company (Gefen, 2000). The various functional modules work in real time with online and batch processing capabilities (Davenport et al., 1998). Different ERP vendors offer different ERP systems with some level of specialty but the core modules are almost the same for all of them. The main ERP modules found in the successful ERP systems are as follows (Turban et al., 2001): Accounting management Financial management Manufacturing management Productio Enterprise resource planning Enterprise resource planning ERP Evaluation and Selection process. A successful ERP project requires selecting an ERP solution, implement the solution, manage changes and examine the practicality of the system, Wei and Wang, (2004). Wrong ERP solution choice would either fail the implementation or weaken the system to a greater impact on the enterprise, Hicks, (1995); Wilson, (1994). Most enterprises often jump into looking at ERP functions and features rather than examining the strategy and business processes. It is important for management to know the current strategy, processes and supporting systems compared to what they could be with the new systems, Donovan, (2001). For most enterprises, the decision to implement ERP functionalities will require buying a software package from one of the more popular vendors on ERP market like SAP and Oracle. But the selection process is not a straightforward task, hence thorough understanding of what ERP packages are to offer, differences in each of them and what might be at stake in selecting one package over the other should be well examined, Sammon and Adam, (2000). Evaluating and selecting an ERP system can be a very complex process on the other hand, but it should be a fact-based process that will bring the enterprise to the point where comfortable well-informed decisions can be made, Donovan, (2001). Thus, in an online poll conducted by ESI International survey of 2,000 business professionals, (2005), fig. 1, below, it clearly show that most software projects, ERP inclusive, failed due to lack of adequate requirements definition. In addition to the above, typical ERP project implementation can still fail due to wrong solution choice, Donovan, (2001). Therefore, a research carried out by Management Agility Inc, (2005), revealed that it is imperative to adopt a thorough evaluation and evaluation process before adopting any ERP solution in SMEs. Hence, there are eight steps detailed below in the flowchart, fig. 2, for a careful and reasonable level of a successful ERP implementation in SMEs. None of these steps must be rush through or skip to avoid any element of failure. These eight steps can be categorised into 5 stages; Planning RFP Solution Evaluation Negotiation Selection and Agreement ERP Software Hardware (Solution) Evaluation and Selection Steps Yes No Stage 4 Stage 3 Stage 2 Stage 1 Define Requirements Shop Round for Product Clarify Requirements Evaluation Vendor Inquiry Interact with Vendors Negotiate Agreement Action Agreement Define business case/need and spell-out required values. Be specific. Ensure the business sponsor is willing to push through business case for change. Look round the market for what product is available. Identify vendors that operates and their general approaches to technologies the take. Discuss with others in the same industry as you are etc. Clarify your requirements and be sure of what you are looking for in line with you business case. Refine requirements if possible and be specific too. Find out what product is looking promising in line with the business need and from which vendor. Identify which vendor and their products and invite interesting ones for demo etc. Request for proposal (RFP). Invite each shortlisted vendor over for a chat and find out more about the product. List out expectations based heavily on business requirements. At this point evaluate this approach. Can you afford to change your current process? Can you afford the change the new product will bring and many more? Initiate Negotiation for the selected product with the selected vendor. Agree on who does what, when are they to be done. Negotiate deliverables, timelines, cost payments schedules and terms, support inclusive. Review all legal terms, finalise the contract and select product for onward implementation. Alignment of business requirement to what the software/hardware can provide. This is the core of the whole exercise else stop the evaluation. Evaluate the product capabilities in line with the business requirement. Evaluate the impact of this product on the business requirement. Stage 5 Analyse Gaps Yes For effective ERP Solution evaluation and selection process, the above steps are categorised into 5 phases as explained below; Stage 1 Plan Requirement Business need is defined, along with areas in business that required technical approach. Develop a specific business case with business value for a solution. Ensure that the project sponsor is willing to articulate the business case for change. Indentify vendors that operate in the line of products you are looking for. Get familiar with the software and hardware infrastructure presence for the solution seeking. Get general view of investment needed, considering software, hardware, other related infrastructure and ongoing support. Based on the survey, evaluate the organisation readiness for the investment and decide whether to continue or not. Now define priorities under must-have and nice-to-have accordingly. Stage 2 Request for Proposals (RFP) Shortlist interesting vendor based on the outcome of market survey for products. Invite interesting vendors for interaction/demonstration of their products. Collects facts/functionalities in line with the business need from various products demonstrations for the developments of unbiased RFP for vendors. Set-up a neutral body to develop RFP using all facts gathered during products demonstration aligned to the business requirements. Distribute out RFP that addresses the vendor as a company and the products they offer. Generate basic expectations from an ideal proposal in line with the business need for onward selection of the ideal software vendor. Stage 3 Solution Evaluation Identify and prioritise remaining gaps between software capabilities as demonstrated and business requirements. Sample form in fig. 3; below. Identify how the gaps will be bridge in terms of configuration, configuration, process change or combination of all these. If the gaps cannot be bridge, then discontinue the evaluation exercise immediately. If the gaps can be bridge consider reengineering of those affected business processes affected and continue with the evaluation. Stage 4 Contract Negotiation Negotiate with each vendor. Establish software, hardware and other infrastructure agreement requirements, which include version, components, maintenance and support. Also negotiate participation in user groups, license costs, maintenance fees and many others. Establish service provider agreement which also include deliverables, timelines, resources, costs and payment schedules. Establish other legal requirements. Stage 5 Selection and Agreement Upon successful negotiation with the right vendor; Review all legal terms on privacy protection, operation guidance and data manipulation etc. Approve agreements with the selected vendors. Agree on implementation plan.

Religion in Ancient China and Egypt Essay
Religion has played a very important role in society and the history of mankind for over thousands of years. Originally created by ancient peoples as a way to explain the unknown, religion has greatly evolved and spread across the globe. As new religions have formed and spread, the diversity and similarities between these new religions have also increased, especially due to their geographic locations. Two civilizations in particular with both similar and distinct religions are ancient China, and ancient Egypt. Ancient Chinese religion and ancient Egyptian religion share many things in common with each other, yet at the same time they are also vastly from one another. Even though there are similarities between many of their gods, beliefs, ideas, and practices, the differences between the two religions helps clearly separate one from the other, and also helps identify their origins. In ancient Egypt, people were constantly faced against natural disasters, famines, droughts, and plenty of other natural phenomena. Without an explanation for all of these events, ancient Egyptians had to create an explanation of their own, and by doing so ended up creating their own religion. By creating a religion, these ancient Egyptians were able to provide explanations to each other for these natural phenomena by making them appear as if they were actions of the gods. In ancient Egypt, religion became a tool to help the Egyptians go about their daily lives without having to worry about disaster striking all the time. The Egyptians began to believe that if they honored the gods correctly everything would be fine and nothing would go badly for them. One key part of the ancient religion was called maat, which was the order of the universe created by the gods at the start of time. Maat was crucial to the daily life of theà Egyptians, and consisted of ideas about truth, justice, an d moderation. The Egyptians were polytheistic, and believed in hundreds of different gods. Of these gods some were lesser and not as important while others were more important and powerful. The king of the Egyptian gods was called Amen-Re. He was accredited for all military victories, and was one of the most powerful gods. Another very important god in ancient Egyptian religion was Aten the minor sun god. At one point Aten was decreed the only god in Egypt by the pharaoh Akenhaten and was to be the only god worshipped, however, after his death Egypt returned to worshipping all of its old gods. A few other gods that were important to Egyptian religion were Osiris; the god of fertility and the underworld, Isis; the goddess of funerals, Anubis; the god of embalming and burial, and Thoth; the god of wisdom and learning. Along with gods, another important part of ancient Egyptian religion was burial rituals. Burial rituals held a lot of significance to the ancient Egyptians because they believed that t heir buildings, prayers, and burial ceremonies were designed to reflect and keep the status of the dead person in their next life. Just like the people of ancient Egypt, the people of ancient China also used religion as a way to explain the unknown and natural phenomena that they encountered. People in the Shang Dynasty worshipped many different types of gods as well including weather gods, sky gods, and river gods, however the most powerful god was Shang-Ti. Shang-Ti was the supreme god who ruled over all of the other gods. Similar to Shang-Ti was Tââ¬â¢ien, which translates to ââ¬Å"Heavenâ⬠, who also ruled over the other gods, but Tââ¬â¢ien also decided who would be the emperor or empress of China by giving them the Mandate of Heaven. The Mandate of Heaven was the right to rule granted to the emperor or empress from the gods, and it was believed that whenever an emperor or empress lost power it was because Tââ¬â¢ien had revoked the Mandate of Heaven. While the people of ancient China worshipped many gods, another very important part of ancient Chinese religion was ancestor worship. The people who lived under the Shang Dynasty strongly believed that whenever their ancestors died, they became similar to gods, and deserved to be worshipped as if they too were gods. Each family inà the Shang Dynasty would not only worship the gods, but would also worship their own ancestors. Along with ancestor worship, during the late Shang Dynasty, people in ancient China also began to use written oracle bones to try to predict the future and also to communicate with the gods. Ancient China and ancient Egypt were both two sophisticated civilizations that created a religion as a way to explain the natural phenomena they encountered and the unknown. Although different in many ways, their religions do share many similarities with each other. One of these similarities is that both of the religions are polytheistic. In both Chinese and Egyptian religion, there are many different gods, and each god rules in their own domain. However, not only do both religions have more than one god in them, but also many of the gods from both religions are very similar to each other in the sense that they rule over the exact same thing. For example in ancient Chinese religion there is a sky god, just like the sky god in ancient Egyptian religion. Another similarity that both religions have in common with each other is that each religion has itââ¬â¢s own ââ¬Å"high godâ⬠that rules above all of the other gods. For the Chinese it is Shang-Ti, the supreme god who rules above all of the others, and for the Egyptians the supreme god is Amen- Re. Along with similarities between their gods, both ancient Chinese and Egyptian religion also share a lot in commonà amongst their burial rituals. In ancient China and ancient Egypt the people held a strong belief in an afterlife after death. Which is why in both ancient China and ancient Egypt, during the of burials of their leaders, pharaohs and emperors were buried with large amounts of treasures and other material items to help prepare them for their next lives. One more similarity between the two religions is that in both ancient China and in ancient Egypt the rulers were viewed as gods. In Egypt the pharaoh was viewed as being the direct descendent from the gods and was seen as a god himself. In ancient China the king of the Zhou dynasty was also viewed as the descendent of the spirit god, and was also seen as a godlike figure. While there are many similarities between the religions of ancient Chinaà and ancient Egypt, there are also many differences between the two that clearly separate them from each other. One of the main differences between the two religions is the practice of ancestor worship. To the ancient Chinese ancestor worship played an extremely important and essential part in their religion. While the ancient Egyptians did have plenty of respect for their ancestors, ancestor worship did not occur amongst them on the scale that it did amongst the ancient Chinese. Along with ancestor worship, another difference that clearly separates the two religions is in their burial practices. While there are some similarities between their burial practices, there are also differences. One difference between the two burial practices is that the Egyptians preferred to preserve their dead because they believed the dead would need their bodies in the afterlife where as the Chinese tended to either bury or cremate their dead. On top of different burial practices, the ancient Egyptians also spent immense amounts of resources building elaborate pyramids to house their dead pharaohs. Even though the ancient Chinese did build elaborate tombs for their dead emperors, they did not spend nearly as much effort or time as the Egyptians did. Furthermore, the ancient Egyptians tended to clean out the organs of their deceased before wrapping them up in linens where as the Chinese would wrap up the bodies of their deceased in silk and would not remove the internal organs. Originally used as an explanation for the unknown, religion evolved into a huge part of society. Two societies where religion became a very significant part of daily life were ancient Egypt and ancient China. Both of their religions appear to have similar origins, and purposes and share similarities in practices, gods, beliefs, and customs. While there is much in common between the religions of the two civilizations, there are also many differences between the two religions including their worshipping and burial practices. Separated by thousands of miles, these two civilizations created their own religions that held many similarities with each other, but also had significant differences to help clearly separate the two.

Brilliant Mathematicians from History Shape Math of Today
Mathematicians not only play an important role in society today, but all the brilliant math minds from the past helped shape every mathematical theory we know, study, and learn today. Math is used every single day, in every continent, every country, every state, and every city. It is the way we solve everyday problems. It is the way we calculate the distance from sun to earth, the way we determine amount of miles one drives from their home to work, the way we estimate our grocery bill before approaching a register, the way we figure out the probability of failing or passing a test, it is the way we as humans approach, solve, and conclude problems we face day in, and day out. There are a various amount of languages spoken to communicate in our world today, but math is one that people from all different parts of planet earth understand, and use for the same purposes. Mathematicians are in a way, unsung heroes, without their discoveries, we would be lost, confused, and not nearly as in telligent. Gauss was one of those heroes. Carl Freidrich Gauss was a German mathematician and a physical scientist also known as the ââ¬Å"Prince of Mathematicsâ⬠. He was born on April 30th, 1777 in Brunswick, Germany and was born to poor, working class parents. His mother was illiterate and his father was a gardener/brick layer.

Civil Rights And Civil Liberties - 1433 Words
The difference between civil rights and civil liberties are, ââ¬Å"what right is affected and whose right is affectedâ⬠. Civil rights are the basic right and privilege to be free from any unequal treatment based on characteristics like, gender, race, disabilities, origin, religion, and or any other characteristic in a setting like employment and housing. Civil liberties are rights and freedoms that are guaranteed to you by the bill of rights and the constitution. The civil liberties include the right to vote, the right to marry, the right to a fair court trial, the right to be free from unreasonable searches of your home, the right to privacy, and the freedom of speech. The constitutional right I choose is the freedom of worship. In sectionâ⬠¦show more contentâ⬠¦Kurtzman.

The court removed a pennsylvania law reimbursing religious schools for classroom materials and teacher salaries. The court found the government was too involved with religion in the case, which is a violation of the constitution. According to the Berkeley Center for Religion, Peace, and World Affairs, ââ¬Å"The Court applied a three-pronged test based on several prior Court decisions: ââ¬Å"First, the statute must have a secular purpose; second, its principal or primary effect must be one that neither advances nor inhibits religion; finally, the statute must not foster an excessive government entanglement with religionâ⬠, meaning the court resulted in the Lemon test.

Low Voltage Effects on Ac Motors Free Essays
Low Voltage Effects on AC Motors A drop in voltage will result in a proportionate increase in current. If the current exceeds the nameplate rating and is not corrected, this can result in damage to the motor from overheating Nameplate Rating An electric motor will have a nameplate rating for both voltage and amperage. When a load is on a motor, the motor must draw a fixed amount of power. We will write a custom essay sample on Low Voltage Effects on Ac Motors or any similar topic only for you Order Now The required power is about equal to volts times amps. Should the voltage fall below the nameplate rating, the amperage will increase. This can result in increased heat that will shorten the motorââ¬â¢s life, according to Motorsanddrives. om. Torque The motor is subject to several kinds of torque. The starting or start-up torque is the amount present when the motor is stationary and power is applied. The pull-up torque is the minimum amount necessary for the motor during the starting sequence. Effects of Low Voltage on Torque A reduced amount of voltage will reduce the amount of torque. This can result in difficulty for start loads. A reduction of voltage to 80 percent would result in a torque value of only 64 percent. In light loads, a reduction in voltage may actually be preferable because it will result in increased efficiency. Even a small voltage unbalance will result in large current unbalance during the running of motor by a factor of 6 times. â⬠¢ Negative phase sequence components will lead to heating of motor â⬠¢ Negative phase sequence currents leads to reduction in motor output torque. â⬠¢ Motor is forced to run at higher slip leading to increased rotor loss and reduced efficiency. â⬠¢ Electricity boards should look in to this phenomenon seriously where irrigation pump sets suffer the voltage imbalance, even 1% loss of efficiency for the country like India would mean a great loss. HP irrigation pump sets with a quantity of 6 Lakh approximate, the loss of power would be 22MW and annual wastage of Rs. 47. 5 millions (At 3 Rs/unit, 4 Hrs of Pump working and 6 monthââ¬â¢s season Keys to maximize the service life of industrial motors Why do motors fail? Certain components of motors degrade with time and operating stress. Electrical insulation weakens over time with exposure to voltage unbalance, over and under-voltage, voltage disturbances, and temperature. Contact between moving surfaces causes wear. Wear is affected by dirt, moisture, and corrosive fumes and is greatly accelerated when lubricant is misapplied, becomes overheated or contaminated, or is not replaced at regular intervals. When any components are degraded beyond the point of economical repair, the motorââ¬â¢s economic life is ended. For the smallest and least expensive motors, the motor is put out of service when a component such as a bearing fails. Depending upon type and replacement cost, larger motorsââ¬âup to 20 or 50 horsepower (hp)ââ¬âmay be refurbished and get new bearings, but are usually scrapped after a winding burnout. Still larger and more expensive motors may be refurbished and rewound to extend life indefinitely. An economic analysis should always be completed prior to a motorââ¬â¢s failure to ensure that the appropriate repair/replace decision is made. Extend Motor Life with Improved Bearing Care Bearing failures are the root cause for the great majority of electric motor downtime, repair and replacement costs. Bearing and motor manufacturers are aware of the situation. Motor repair shops can attribute much of their business to bearing failures. And motor users see bearing failure as the fundamental cause of virtually every electric motor repair expense. Studies conducted by the Electrical Apparatus Service Association also demonstrate that bearing failures are by far the most common cause of motor failures. Knowing that shaft bearings are the Achillesââ¬â¢ heel of industrial electric motors is not a new idea in maintenance departments, but what is new is recognizing that something can be done to prevent most motor bearing failures. Factors Affecting Bearing Life Electric motors actually present a relatively easy duty for shaft bearings. The motor rotor is lightweight, yet because of its large shaft diameter, the bearings are large. For example, the bearings supporting the 140 lb. Rotor for a typical 40 hp. 1800 rpm industrial motor are so large that they have an L-10 minimum design fatigue life of 3000 years, or 10 percent of the bearings are statistically expected to fail from fatigue after 3000 years of operation. Plant operating experience, however, strongly contradicts such optimistic estimates of motor bearing life. In actual industrial environments, bearing failure is rarely caused by fatigue; it is caused by less-than-ideal lubrication. Because of contaminated lubrication, bearings fail well before they serve their theoretical fatigue life. There are many reasons for less than-ideal bearing lubrication. Lubricants can leak out; chemical attacks or thermal conditions can decompose or break down lubricants; lubricants can become contaminated with non-lubricants such as water, dust, or rust from the bearings themselves. These lubrication problems can be eliminated. Motor bearings can last virtually forever by simply providing an ideal contamination-free, well-lubricated bearing environment. Conventional wisdom teaches that such an ideal motor bearing environment can be provided by using a dry-running lip seal or using sealed (lubricated-for-life) bearings. Indeed, for many light-duty applications, such bearing protection techniques are often sufficient to allow bearings to last as long as the equipment itself. However, these bearing protection methods have not significantly reduced the rate of bearing failure in severe-duty industrial motors. Bearings in industrial applications continue to fail because of inadequate lubrication caused by lubricant loss, contamination, and decomposition and break-down. Lip seals invariably wear out well before the bearing fails, and sealed bearings inherently foreshorten the life of a bearing to the service life of the contained grease (usually only about 3,000 to 5,000 hours for most industrial services). Maintenance professionals may find the following suggestions on how to forestall motor hearing failure obvious, but some new techniques and technologies are available. Lubricate Bearing at Correct Intervals Despite years of warnings from bearing manufacturers, over lubrication continues to plague many motor bearings. Too much grease can cause overheating of the bearings. The lubrication instructions supplied by the motor manufacturer will specify the quantity and frequency of lubrication. Generally, two-pole motors should be greased twice a year, four-pole and slower motors only once a year. Use the Best Available Grease The most commonly used bearing grease is polyurea-based, a low-cost, low-performance, highly compatible lubricant. However, it does not handle water well, a serious drawback for many industrial applications. It reacts readily with water and loses its ability to lubricate bearings. Industrial motor bearings should be lubricated with a synthetic-based aluminum complex grease. A high-quality grease pays for its additional cost in reduced motor downtime and repair costs. Keep Out Moisture Unless the motor is being hosed down or it operates in a humid environment, reasonably shielded motor bearings may not become seriously contaminated with moisture while the motor is running. However, when the rotor is shut down, moisture and condensation can collect on the surface of the bearing components. Eventually, this water breaks through the oil and grease barrier, contacts the metal parts of the bearing, and produces tiny particles of iron oxide. These rust particles make an excellent grinding compound when mixed with the grease. resulting in premature failure of the bearing because of surface degradation. Preventing water contamination is a major challenge to bearing housing design. Close shaft-to-endbell clearances cannot stop the movement of humid air. Contact seals will quit contacting, resulting in large gaps that allow movement of air and water vapor across the bearing. Vapor-blocking bearing isolators, such as the one illustrated, are among the more successful devices presently available to prevent water vapor from entering a stationary bearing. When the motor shaft is rotating, the isolator opens, eliminating the possibility of friction and wear. However, when the shaft is stationary, the isolator closes, preventing movement of air or water across its face. With no wear from rotating friction, the seal may last indefinitely, and surely as long as the fatigue-failure life of the bearing. Keep Out Dirt Lip seals, contact seals, and frequent grease replacement help minimize the amount of dirt and other air-borne abrasives that can contaminate bearing lubricant. These solutions, however, have some drawbacks. Lip seals have a short service life, and frequent grease displacement is expensive and messy. One successful approach to keeping air-borne dirt and liquids out of an operating bearing is to install a labyrinth-type non-contact seal over the bearing housing. These bearing isolators, readily available from suppliers, combine a tortuous labyrinth path with impingement and centrifugal forces to trap and remove air-borne dirt and liquid; virtually no contamination can reach the bearing. Because the bearing isolator is a non-contact device, it will generally be the longest-lasting component of the motor. Although not intended as such, a bearing isolator could serve as an emergency sleeve bearing if the primary bearing fails, possibly preventing damage to the motorââ¬â¢s stator and rotor. In emergency situations, the bearing isolator can allow continued operation for a short time and still prevent the need to rewind the motor when the bearing is replaced. Bearing isolators constructed of bronze or other non-sparking materials also can prevent hazardous sparks that could otherwise occur when the bearingââ¬â¢s rolling elements fail. Other Suggestions Improved bearing protection and lubrication will reduce downtime and the maintenance costs of electric motors, but other important motor design features contribute to long service life, including over-sized high quality bearings, high-tech winding insulation, superior fan design, high-performance paint (such as epoxy) and a strong, rigid cast iron frame. These features, usually standard or readily available, are found in most industrial-grade severe-duty electric motors. High-performance bearing protection systems. however, are not universally accepted as essential for long motor life. Specifying permanent bearing protection for new motors, or retrofitting isolators onto existing equipment, usually requires initiative on the part of the userââ¬â¢s maintenance or engineering staff. Permanent, absolute bearing protection has a greater effect on motor life than any other decisions made in specifying, equipping, and caring for electric motors. Keeping bearings lubricated with the right amount of clean, uncontaminated, high-quality lubricant allows bearings in most industrial motors to outlast all other motor components.

Volcanos Essay Example For Students
Volcanos Essay Volcanos occur all over the world.The best know volcano zones occur on the destructive plate margin around the Pacific Ring of Fire.This chain of volcanos that lie along the west coast of central and south America,Japan and the Philippines,across New Zealand and into the Atlantic.Volcanos also occur in mid-ocean along the line of ocean ridges.The Mid-Atlantic Ridge is an example of ocean floor volcanos.When these volcanos erupt lava flows from the cracks building up the ocean floor.Volcanos can also occur away from plate boundaries.These are the Hawaiian Volcanos.As you can see there are lots of places were volcanos occur.Sometimes these volcanos are where humans have settled.To help protect our belongings and save human lives we have developed ways to predict when volcanos are about to erupt.Here are some. PredictionsTwo main methods are used to predict when volcanos are about to erupt.These methods are called geophysical techniques,and chemical techniques. The geophysical method can detect any changes in the rock below.As the magma rises it forces the rocks apart,Which can create minor earthquakes on and or around the mountain.These can be detected on a seismographs.A seismograph picks up the seismic waves the earthquake gives off and records them.A seismograph works by a pen and a weight suspended on a spring.As the earth shakes the pen writes the waves,called a seismogram,on a revolving drum.A comparison can be used.They take two or more seismographs readings to pin point exactly where the magma is trying to surface.This technique is successful in Hawaii where they are a lot of volcanos.The place and the time of eruptions have been forecast accurately.Before a volcano is about to explode the ground around it swells with magma.This causes the ground to start to tilt.The tilt can be measured by an instrument called a tiltmeter.Two containers are half filled with water.And a tube connects the two.As magma rises and changes the a!ngle of the earth.Water goes into the lower container.Scientist can tell if the volcano is getting more active.When magma moves its gravity changes.This change in gravity can be detected by using gravimeters.When rock is heated to a certain temperature.It looses its magnetism.And this can be detected with a magnetometer.When magma rises to the surface it gives off heat.This heat can be detected with a intfa-red temperature surveys.Sometimes chemical methods are used.They measure the volcanic gases at hit springs and at fumaroles which are openings in the ground were gases escape from.Just before a volcano is about to erupt there is an increase in certain gases.These gases are chlorine compounds,sulphor oxides,carbon dioxide,hydrogen, and radon. DamagesWhen a volcano erupts huge amounts of lava are spewed out of the volcano.These huge flows of lava can wipe out towns.This type of volcanic eruption is called Hawaiian.These volcanos put on fire shows .They are rarely violent or explosive ,because the lava is fluid enough to let the gases escape easily.The lava flows out of boccas.These volcanos are not really dangerous.But they can cause alot of damage if people or buildings get in its way.A strombolian eruptions are more violent producing a lot thicker lava.Because the lava is thicker the gas can not escape easily from it making the lava hostile.The plinain eruptions ar the most dangerous .They hurl huge amounts of pumice as high as fifty kilometers into the atmosphere.Then is ash falls over wide areas.Then this is followed by pyoclastic flows,where hot gases and ash pour out of the vent.These flows rush across the landscape ,burning and burying anything in its path.This is the eruption that happened to Mount St. Helen in th! e U.S.A. Wisps of steam were coming out of the vents on the side of the mountain.During a period of several weeks a three hundred foot high wedge shaped bulge developed on the south side of the mountain as a result of rock and ice being pushed up.There were gaping cracks in the glaciers.They were gray with a dusting in volcanic ash.Weeks later the bulge blew sending ash and mud slides down the mountain wiping any thing that got in its way.The eruption cause a lot of damage.It created the worlds biggest clear cut.Two hundred and thirty square miles of trees lay in a tangled mess after the eruption.But people were trying to save as much of the lumber as they could.They were hauling out Five hundred loads a day of the fallen trees.But of all those able to be salvaged one point eight billion board feet of timber was destroyed.The eruption also took out some human life.Sixty five people were killed in the eruption.But the most damage was done to the surrounding wildlife.Five thou!sand wh ite tailed deer were killed,One thousand five hundred elk,two hundred black bears,fifteen mountains goats,plus unknown numbers of mountain lions,bobcats,small rodents,birds,fish,and insects were also killed.The whole population of spotted owls were completely wiped out.That was some things that can happen here are some more.Ash can bury structures and cause people to suffocate or if ash mixes with water it creates huge mud flows that race down mountain sides,clogging rivers.Hot chucks of lava and ash can start fires far from the lava flows.The earthquakes that accompany the eruptions can destroy buildings.The value of the damage consists of how bad the eruption was and if it was near any civilization.A very bad eruption near a city can cause millions and millions of dollars of damage and a great loss of lives. Even a small eruption with a lot of lava flow can cause millions of dollars of damage.If a volcano out in the wilderness explodes .The value of the damage can dif!fer.From how much value you place on the wildlife and trees.When Mount St. Helen exploded ash from the volcano clogged major rivers.The rivers were the Toutle and Cowlitz.The U.S Army Corps of Engineers took the task to unclog it.The cost of this was a quarter of a billion dollar.This gives you an idea how much money it costs to fix something damaged by a volcano. .u1b5ce51abc00fd59b59b26421c756429 , .u1b5ce51abc00fd59b59b26421c756429 .postImageUrl , .u1b5ce51abc00fd59b59b26421c756429 .centered-text-area { min-height: 80px; position: relative; } .u1b5ce51abc00fd59b59b26421c756429 , .u1b5ce51abc00fd59b59b26421c756429:hover , .u1b5ce51abc00fd59b59b26421c756429:visited , .u1b5ce51abc00fd59b59b26421c756429:active { border:0!important; } .u1b5ce51abc00fd59b59b26421c756429 .clearfix:after { content: ""; display: table; clear: both; } .u1b5ce51abc00fd59b59b26421c756429 { display: block; transition: background-color 250ms; webkit-transition: background-color 250ms; width: 100%; opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #95A5A6; } .u1b5ce51abc00fd59b59b26421c756429:active , .u1b5ce51abc00fd59b59b26421c756429:hover { opacity: 1; transition: opacity 250ms; webkit-transition: opacity 250ms; background-color: #2C3E50; } .u1b5ce51abc00fd59b59b26421c756429 .centered-text-area { width: 100%; position: relative ; } .u1b5ce51abc00fd59b59b26421c756429 .ctaText { border-bottom: 0 solid #fff; color: #2980B9; font-size: 16px; font-weight: bold; margin: 0; padding: 0; text-decoration: underline; } .u1b5ce51abc00fd59b59b26421c756429 .postTitle { color: #FFFFFF; font-size: 16px; font-weight: 600; margin: 0; padding: 0; width: 100%; } .u1b5ce51abc00fd59b59b26421c756429 .ctaButton { background-color: #7F8C8D!important; color: #2980B9; border: none; border-radius: 3px; box-shadow: none; font-size: 14px; font-weight: bold; line-height: 26px; moz-border-radius: 3px; text-align: center; text-decoration: none; text-shadow: none; width: 80px; min-height: 80px; background: url(https://artscolumbia.org/wp-content/plugins/intelly-related-posts/assets/images/simple-arrow.png)no-repeat; position: absolute; right: 0; top: 0; } .u1b5ce51abc00fd59b59b26421c756429:hover .ctaButton { background-color: #34495E!important; } .u1b5ce51abc00fd59b59b26421c756429 .centered-text { display: table; height: 80px; padding-left : 18px; top: 0; } .u1b5ce51abc00fd59b59b26421c756429 .u1b5ce51abc00fd59b59b26421c756429-content { display: table-cell; margin: 0; padding: 0; padding-right: 108px; position: relative; vertical-align: middle; width: 100%; } .u1b5ce51abc00fd59b59b26421c756429:after { content: ""; display: block; clear: both; } READ: Oppenheimer and The ATomic Bomb EssayPrecautionsBecause we sometimes have to live near volcanos.We have to take some precautions in case they ever erupt.All new buildings being built in the vicinity of volcanos should be earthquake proof .Mud flows,landslides,and lava can cause a lot of damage.There for dams and public buildings should be located so they dont get destroyed by these forces.People should be aware of the warning signs of a volcano ,earthquakes and ash being spewed out.They should what to do if they have to leave the town quickly in case the volcano does blow.
