During which phase does the project team focus on testing the implementation?

The Realize phase is dedicated to completing the functional and technical design of the system, followed by building, testing, and validating the solution. During this phase, the project team conducts various types of testing, such as unit testing, integration testing, and user acceptance testing, to ensure that the implementation meets all specified requirements and works as intended. This focus on testing is essential to identify and resolve any issues before the system goes live, ensuring a smooth transition to the next phases.

In contrast, the Prepare phase primarily involves project setup and planning, where project goals, teams, and timelines are established. The Explore phase focuses on gathering requirements and understanding business processes, emphasizing solution design and fit-to-standard workshops. The Run phase comes after the go-live, concentrating on system maintenance, support, and optimization of the implemented solution. Therefore, the Realize phase is rightly identified as the pivotal time for the project team's focus on testing the implementation.
