Life Cycle, unified process
The Unified Process life cycle for software development consists of four phases, namely: Inception, Elaboration, Construction and Transition. Each phase is concluded by a major milestone. That is:
  1. Inception specifies the end-product vision, its business case and the scope of the project. It is concluded by achieving the Lifecycle Objective Milestone.
  2. Elaboration involves the planning of necessary activities and required resources, specifying the features and designing the architecture. It is concluded by achieving the Lifecycle Architecture Milestone.
  3. Construction involves building the product and evolving the vision, the architecture and the plans until the product, i.e. the completed vision, is ready for delivery to its user community. It is concluded by achieving the Initial Operational Capability Milestone.
  4. Transition involves transitioning the product to the care, custody and control of the users, including manufacturing, training, support and maintenance until users are satisfied. It is concluded by achieving the Product Release Milestone.
