Organizations can acquire software by building it, buying it, renting it, or some combination of these approaches. The acquisition can be of an entire application, pieces of an application, or both. With this in mind, there are only a few recognized modern frameworks for software development-i.e., the building of applications. Among these are the Rational Unified Process (RUP) and "Agilism" (i.e., the so-called agile methods, which include Extreme Programming, Feature-Driven Development, Lean Development, Adaptive Software Development, and Scrum).

a. Describe, compare, and contrast RUP and Agilism as strategies for software development. Be sure to explain clearly the nature of each-i.e., how they work, when and for what they should be used, and what problems they solve and produce.

b. Discuss as well their assumptions about and implications for: clients, software professionals, the IS/IT organization, and the business organization.
