This article provides an overview of the fourth stage of a typical waterfall project methodology.

The purpose of this phase is to build and unit test the solution, it ensures the right solution is produced based on the design, with the right level of unit testing being completed and documented prior to releasing the change for more in-depth and rigorous user acceptance and system integration validation.
Entry criteria include:

  1. Design specifications and build/transition plans.
  2. Design (CP3) Checkpoint approval from the PMO.

Exit criteria include:

  1. Completed unit test artefacts, cases and signoffs.
  2. Completed solution build.
  3. Build (CP4) Checkpoint approval from the PMO.

Typical outputs include:

  1. Build sign-off.
  2. Unit test results.
  3. Transition plan.
  4. CP4 pitch.

Typical PMO questions include:

  1. Has the solution build been completed and development tested?
    Has the solution build been reviewed and approved by all stakeholders?
  2. Has the transition plan been verified?
  3. Are the appropriate user testing resources identified and secured?
  4. Have the test cases been developed based on the use cases?
  5. Is the process for UAT documented and approved by the impacted stakeholders?
