Which review confirms that system requirements are defined and understood before development proceeds?

• A. Systems Requirement Review (SRR)
• B. Test Readiness Review (TRR)
• C. Lean Manufacturing
• D. Alternative Dispute Resolution (ADR)

Answer: (A)

The main concept here is ensuring a solid, agreed-upon foundation before building starts. A Systems Requirements Review is the formal checkpoint that confirms the system requirements are defined, complete, and understood by all stakeholders, and that they are baselined and approved before design and development proceed. This review validates that requirements are traceable, feasible, and testable, which helps prevent late changes, scope creep, or rework later in the project.

The other items don’t fit this stage. A Test Readiness Review checks whether the system and its test plans are prepared to begin testing, not whether requirements are defined. Lean Manufacturing is a methodology for reducing waste in production processes, not a formal requirements review. Alternative Dispute Resolution is about resolving conflicts and is not a project lifecycle review.
