During which stage of the fundamental test process is the testability of requirements evaluated?

The fundamental test process consists of five main activities: test planning and control, test analysis, test design, test implementation and execution, and test evaluation and reporting. During the test analysis activity, the testability of requirements is evaluated, meaning that the requirements are checked for clarity, completeness, consistency, verifiability, etc. Test analysis also involves identifying test conditions based on the test basis, such as requirements, specifications, user stories, or use cases.
