Which phase involves testing the solution to ensure it works correctly, and may cycle back to earlier phases?

Which phase involves testing the solution to ensure it works correctly, and may cycle back to earlier phases?

• A. Planning and Analyses Phase
• B. Designing Phase
• C. Implementing and Publishing Phase
• D. Testing Phase

Answer: (D)

The main concept here is verification and iterative refinement through testing. In the Testing Phase, you rigorously check that the solution works as intended, verify it meets the requirements, and uncover defects. This phase often reveals issues that require revisiting earlier steps—adjusting the design, refining the implementation, or updating requirements—so the process can cycle back to those earlier stages until the solution passes the tests. The other phases focus on planning, outlining how to build the solution, or actually building and releasing it, but testing specifically targets validation, quality, and the feedback that drives improvements.
