The Four Phases of UP
The following are the four phases of the Unified Process:
- Inception - approximate vision, business case, scope, vague estimates.
- Elaboration - refined vision, iterative implementation of the core architecture, resolution of high risks, identification of most requirements and scope, more realistic estimates.
- Construction - iterative implementation of the remaining lower risk and easier elements, and preparation for deployment.
- Transition - beta tests, deployment.
