The Rational Unified Process (RUP)

Paper Summary:

This paper explains that the philosophy of RUP differs from that of the systems development life cycle (SDLC) in that it is architecture-based instead of process-based; RUP breaks the components of the systems development life cycle into phases, which may be subject to several iterations containing core workflows, which lead to an end milestone. The author points out that the basic structure of RUP is based on phases named inception, elaboration, construction and transition; these new sets of systems analysis are the workflows. The paper relates that one of the key advantages of the RUP system is that it allows larger systems to be broken down into components and then these components to be broken into hierarchies, which allows the developer to handle many unrelated architectural units rather than trying to integrate many unrelated components into a systematic waterfall-like system.

From the Paper:

"Authors have found many grounds upon which to criticize RUP. RUP has been found to be lacking in several areas. Arguments found in Hesse (2001) contend that it does not contain a contingency for enterprise reuse management, requirements modeling, enterprise specific architecture, enterprise specific risk management, human resource management, system operations, and systems support. He has developed a system that extends RUP to include these issues called Enterprise Unified Process (EUP). The authors of EUP point out that these issues are concerns in the real world for corporations. No one would argue that these issues are indeed real issues for corporations. However, it could be argued that these areas are outside of the realm of the systems developer and would be better left to the experts in these fields. They should be considered by the design team and the proper entities consulted in these issues. However, by strict definition of the job description of the systems developer, they would fall outside of their prescribed area of expertise."
