Chapter 9. Unified Process

The true measure of a man is how he treats someone who can do him absolutely no good.

Samuel Johnson

OVERVIEW

• Classification of UP.

• Workproducts, roles, and practices.

• Common mistakes, adoption and process mixtures, strengths and weaknesses.

The Unified Process (UP) is a popular iterative process framework, particularly its refinement in the Rational Unified Process or RUP. Some of the UP key practices and guidelines illustrate its spirit:

UP versus RUP

• Develop in short timeboxed iterations.

  practice details

• Develop the high-risk and high-value elements (for example, the core architecture) in early iterations, preferring re-use of existing components.

• Ensure that you deliver value to your customer.

• Accommodate change early in the project.

• Work together as one team.

The UP organizes iterations within four phases. The elaboration phase iterations emphasize programming the risky, core architecture, construction phase iterations build the remainder.
