  • The keyword in Enterprise Resource Planning is Enterprise. This is the ambitious goal of an ERP, to integrate an organization into one information system. That is a tall order, building a single software program that serves the needs of people in finance as well as it does the people in human resources and in the warehouse. Each of those departments typically has its own computer system, each optimized for the particular ways that the department does its work. But ERP combines them all together into a single, integrated software program that runs off a single database so that the various departments can more easily share information and communicate with each other.
  • Here you can see a general evolution of ERP systems. They started as customized and proprietary Inventory control systems in the 1960’s. In the 1970’s the focus shifted to Material Requirement Planning which provided raw materials and component management and procurement. In the 1980’s the model continued to grow by including distribution channel functions. In the 1990’s This model grew further into the fully defined business suites that we have come to know as Enterprise Resource Planning Systems. The development of these products was perpetuated by the desire to move programs off of customized mainframe programs, the development of new technologies, the decentralization of businesses, and the desire to implement BPR. CRM, which first gained prominence in the mid-1990s, was the logical progression of ERP, as it was designed to enhance a company's front-desk activities. Customer interaction entered a new era with the advent of call centers supported by CRM software, which allowed companies to direct marketing activities and build relationships with distinct groups of customers. CRM also promised to improve the profitability and effectiveness of the company by automating many processes, making better use of available staff and reducing overall costs. CRM offers a utopian answer to many challenges. With an integrated CRM solution, companies can detect changes in customer buying habits, understand their needs faster than the competition and respond to customer demands in double-quick time. Today, the model grows and ERP companies are trying to fully Internet Enable their products and redesign their products for the new business models. What was once internally focused is now externally focused.

Costs of ERP  Meta Group survey of 63 companies (small to large, range of industries)  Average of $15 M per firm (range $400,000 - $300M)  On average the TCO is $53,000 per user  Media annual savings: $1.6M  Requires two-years of implementation and integrationSource: CIO.com: "The ABCs of ERP" 18

    22. 22. Reasons to Adopt ERP One face to the customer Knowing “what is possible” in terms of organizational inventory Eliminating redundancy Consolidation 22
    23. 23. Reasons to Adopt ERP (cont’d) Handle growth Reduce stress on existing IT Avoid legacy systems Modernizing 23
    24. 24. Reasons Not to Adopt Cost Loss of competitive advantage Resistance to change Poor cultural fit 24
    25. 25. Alternatives? Open Source ERP (+ Support Vendors)  e.g. GNU Enterprise, Apache OFBiz ERP for SMEs  less expensive systems with fewer "bells and whistles" ERP ASPs (Application Service Providers)  ASPs will host and maintain the software for you 25
    26. 26. Post-ERP? Service-Oriented Architectures (SOA) hold some promise as the natural evolution from ERP The foundation of SOA is standardization based upon web services interoperability standards. SOA does not replace ERP  provides the ability to “loosely couple” services (business functions). 26
