15 SUMMER 2005 JUNE ERP Implementation Choices ERP Implementation Methodologies SAP Implementation Methodology (ASAP) Strategic Implementation Decisions

16 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Strategic ERP Implementation Choices Timeline Big Bang Implementation Phased (Roll Out) Implementation Mini Big Bang (Combination of big bang and roll-out) Staff/Resources Outsourcing In-house Customization Level Pro’s and Con’s?

17 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Customization in ERP Environment Technical Customization Process Customization

18 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel ERP Technical Customization Davenport: Module Selection Table Configuration Code Modification Brehm, et.al. : Configuration Bolt-on’s Screen masks (eg: 3 screens into 1) Extended Reporting Workflow Programming User Exits ERP Programming (eg: ABAP/4) Interface Development Package Code Modification

19 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Module Selection Implement one or more modules Default configuration of the vendor May be appropriate for small companies Rarely sufficient for many companies

20 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Configuration Configuration: Changing parameters in tables in SAP R/3 SAP promises that configuration specifications will transfer without problems to later versions of their software SAP calls configuration customization

21 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Configuration in SAP R/3: SPRO

22 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel The Implementation Guide (IMG)

23 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Defining Companies

24 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Code Modification (Customization) Customization: Changing code in SAP R/3. Today such changes are done in a programming language developed by SAP called ABAP/4. (In future it will also be possible in J2EE.) May involve defining new database tables It is possible to make changes to the code that SAP will not support. Future upgrades will need to be re-customized (expensive).

25 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Process Customization Process Customization: The degree to which the business process is changed to fit the system. Business process: Tasks Resources Outcome Relationships among tasks Relationships among resources and tasks

26 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Process Customization Categories No change Change in tasks and resources No changes in relationships among task and configuration of resources Eg: Task automation Incremental change Improvements in tasks and resources Improvements in relationships among tasks Improvements in relationships among tasks and resources. Nature of process and outcome measures unchanged Eg: Total Quality Management (TQM)

27 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Process Customization Categories Radical Change Fundamental rethinking and radical redesign of elements in a business process including measures of performance Eg: Business Process Reengineering Eg: Move from functional view of organizations to process view of orgs.

28 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel ERP Customization Choices

29 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Questions?

30 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Sources Kenny Leung- SAP Summit 2005 Hong Kong Luo, W., & Strong, D. M. (2004). A framework for evaluating erp implementation choices. IEEE Transactions on Engineering Management, 51(3), Brehm, Heinzl, and Markus, “Tailoring ERP Systems: A Spectrum of Choices”, 2000

31 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel Some Terminology Basis Software. The R/3 Basis is similar to an operating system that specifically has the capability of processing any of the SAP R/3 transactions. It’s a middleware between the operating system and the servers that allow for smooth operations across different servers, operating systems, and databases. ABAP: Advanced Business Application Programming (ABAP/4), is a special ‑ purpose, fourth generation language developed by SAP, is used to write programs for the specialized requirements of creating custom reports, screens, user ‑ defined functions, and special industry solutions for use with the SAP R/3 System.

32 IST 600 ERP Systems: Key Implementation Issues U. Yeliz Eseryel What is SAP Netweaver? A comprehensive integration and application platform, SAP NetWeaver works with your existing IT infrastructure to enable and manage change. SAP NetWeaver embraces Internet standards such as HTTP, XML, and Web services. Ensuring openness and interoperability with Microsoft.NET and Java 2 Platform Enterprise Edition (J2EE) environments such as IBM WebSphere.
