What should the business analyst do to ensure that all requirements meet a quality checklist before the development and testing phase?

To ensure requirements meet a quality checklist, they must be verifiable. Assigning a specific verification method (e.g., inspection, demonstration, test case) to each requirement establishes how it will be proven that the solution meets that requirement. This process ensures that every requirement is clear, unambiguous, and testable before development begins. It forms the basis for quality assurance activities and confirms that the requirement has been successfully delivered.

A. Validating only "important" requirements is insufficient; all requirements must meet quality standards to ensure the overall solution quality.
B. Seeking approval for partial testing undermines the goal of ensuring all requirements meet the quality checklist and introduces risk.
C. Standardizing requirements is a good practice for consistency, but it does not in itself guarantee that each requirement is verifiable or meets quality criteria.
