Enterprise Resource Planning Presentation Transcript

  • 2. Enterprise Resource Planning (ERP) Systems
    • 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 application programs
    • Goal is to have a single master data base (except for partitions and replications) so that the entire enterprise is working off the same, continuously updated, data

  • 9. The Good News: ERP Systems

    • creates commonality of databases
    • can incorporate improved best processes – e.g. , JIT and systems integration
    • increases communication and collaboration between business units and sites
    • has an off-the-shelf software database
    • can be implemented module by module
    • may provide a strategic advantage for a limited time
  • 10. The Bad News: ERP Systems
    • Are very expensive to purchase and even more so to customize
    • May require major changes in the company (and you know how easy that is!!) and its processes to implement
    • Can be so complex that many companies cannot adjust to it
    • Involve an ongoing, possibly never completed, process for implementation
    • Require expertise in limited supply with ongoing staffing problems
    • But it may be a necessary evil for competitive purposes
