CAPM Practice: Validate requirements through product delivery

Product increment reviews (like sprint reviews) create structured validation checkpoints. Stakeholders interact with real, working functionality and provide validation feedback — confirming that delivered work meets needs and identifying gaps or refinements for the next iteration.

**Why not B:** A product increment review focuses on evaluating delivered functionality against requirements, not on reviewing financial costs. Financial reviews are a separate project management activity and do not serve the purpose of iterative requirements validation.

**Why not C:** While code quality reviews (such as peer reviews or code inspections) are valuable, they are a development team activity focused on technical implementation. A product increment review is a stakeholder-facing event that validates whether the delivered product meets business expectations, not whether the code is well-written.

**Why not D:** A documentation completeness audit is an administrative check, not a product validation activity. Product increment reviews are about demonstrating working functionality to stakeholders and gathering feedback, which is fundamentally different from verifying that all required documents have been produced.
