Dealing with Purchased or Leased Business Applications
Rick Sweeney · 2012
This chapter discusses how purchased and leased business applications are different but need to be treated no differently from how one deals with internal developed applications. The business's ability to purchase or lease business capabilities plays a critical role in supporting it. Moreover, validating business requirements against existing business application software and finding a significant match absolutely accelerates the delivery of those capabilities. Consequently, once the application is implemented and used by the business, it is no different from any other application from the business's perspective. This chapter further describes how the SOA architects need to be proactively involved with the business application vendor evaluation and selection process right from the start. The process starts with the implementation of a formal RFI/RFP process that incorporates the SOA architecture requirements and considerations and a topdown business-driven governance commitment to validate those requirements and considerations.
