2.2. Additional UP Best Practices and Concepts

The central idea to appreciate and practice in the UP is short timeboxed iterative, adaptive development.

Another implicit, but core, UP idea is the use of object technologies, including OOA/D and object-oriented programming.

Some additional best practices and key concepts in the UP include:

• tackle high-risk and high-value issues in early iterations

• continuously engage users for evaluation, feedback, and requirements

• build a cohesive, core architecture in early iterations

• continuously verify quality; test early, often, and realistically

• apply use cases

• model software visually (with the UML)

• carefully manage requirements

• practice change request and configuration management

See Chapter 37 for a more detailed description of these practices.
