Business Process Reengineering

Business process reengineering (BPR) in Chapter 10 was specifically discussed in relation to legacy applications. This chapter provides further methods on actually replacing legacy systems as part of the redesign for a new system. That is, rather than create legacy links, replace the old application with the new system altogether. This approach can often be an attractive alternative because a packaged solution might indeed contain many of the features and functions of the legacy. The object-oriented (OO) paradigm is again the way to accomplish this analysis, particularly using the essential components that were outlined in Chapter 10. The essential components first require the establishment of the core business requirements and then the mapping of the functionality of the organization or business unit to these components.
