The construction phase is divided into multiple iterations, for each iteration to result in an executable release of the system. System is built using the basis created during elaboration phase. During this phase, the design of the system is finalized and refined and the Ĭonstruction-the longest and largest phase within Unified Process.Reduce or eliminate their impact on final schedule and product, to establish design and architecture (e.g., using basic class diagrams, package diagrams, and deployment diagrams), to create a plan (schedule, cost estimates, and achievable milestones) for the next (construction) phase. Įlaboration-during this phase the project team is expected to capture a majority of system’s requirements (e.g., in the form of use cases), to perform identified risk analysis and make a plan of risk management to.Otherwise it could lead to unnecessary make-overs and schedule delays in further phases. To take a pause at the very beginning of the project to refine the vision and goals. With no clear goals and vision the project most likely is doomed to fail. If the inception phase lasts for too long, it is like an indicator stating that the project vision and goals are not clear to the stakeholders. Project scope and setting boundaries, outlining key requirements, and possible architecture solution together with design tradeoffs, identifying risks, and development of initial project plan-schedule with main milestones and cost estimates. It is used to prepare basis for the project, including preparation of business case, establishing Inception-the first and the shortest phase in the project. The iterations are spread over four phases where each phase consists of one or more iterations :

System is developed incrementally over time, iteration by iteration, and thus this approach is also known as iterative and incremental software development. Unified Process is based on the enlargement and refinement of a system through multiple iterations, with cyclic feedback and adaptation.
