An organization delivers system implementation projects to external clients.

The key to resolving recurring issues during end-user testing is to establish a structured and standardized testing process. PMI-PMOCP guidance highlights that creating a formal test strategy ensures project teams have a clear, consistent approach to testing activities, reducing variability and improving quality outcomes.

While logging and reviewing testing issues (option B) and deploying tools (option C) are valuable, they should follow the definition of a strategic testing framework that aligns all teams. Assessing maturity gaps (option D) is important but is a broader step that should not delay immediate process improvement.

A test strategy formalizes roles, responsibilities, documentation standards, and test procedures, thus preventing the issues seen in unstructured testing and enabling continuous improvement.
