Enterprise Resource Planning
40
Enterprise Resource Planning
Enterprise Resource Planning Systems is a computer system that integrates application programs in accounting, sales, manufacturing, and other functions in the firm This integration is accomplished through a database shared by all the application programs ERP can be considered an initiative launched to better manage business processes across the organization using a common, integrated database, shared data management applications and reporting tools.
41
Enterprise Resource Planning - Background
An organization’s critical business processes often cut across many of its functional units. In most organizations, each process has its own data needs and applications that operate as distinct systems. The results of this approach: - Function-Centric view in the business units - Operational Inefficiencies Example: A customer order Sales Accounting Purchasing Production Logistics
42
The Idea of MRP Enterprise Resource Planning - Background
ERP evolved from MRP (Material Requirements Planning) and MRP II. Customer orders Forecasts Material requirements plan Inventory records Inventory transactions Bills of materials Routings Time standards MRP explosion Master production schedule Manufacturing resource plan Cost and financial data
43
The Idea of MRP II Enterprise Resource Planning - Background
“Instead of having one set of numbers for the operating system in manufacturing and one set kept by the financial people – once the manufacturing people have numbers that are valid, the financial people can use these to get their numbers. Of course, whenever there are two systems – the numbers are bound to be different. With MRP II, everybody can be working with the same set of numbers, but that’s only the technical difference. The big difference comes in the way management uses these tools…MRP II becomes a company game plan for manufacturing, marketing, engineering, and finance.” Oliver Wright, The Executives Guide to Successful MRP II, 1982.

How much disk storage space will the master file consume? How quickly can I access the data? How many lines of code will it take to perform this function? How easily can I retrieve the data? How can we cut down CPU time when we run this program? How much clerical support will I need to enter the data into the system? What is the most efficient way of storing the data? How will the operation of the system fit into my daily business schedule? What database management system should we use?
