A Solution Architect actively takes part in the creation and review of the high-level requirements document. This document should have the following attributes: Clarity — you need to ensure that requirements are clear to understand, free from any ambiguous and conflicting statements.
Actionability — all the requirements should be precise about what should be done without general or vague statements.
Feasibility — all requirements must be feasible. And you need to be sure that features specified in requirements will be used and needed.
Testability — all the requirements can be tested and have acceptance criteria.
All other options are incorrect.
