In the context of business analysis, the input status of requirements for undertaking requirement verification activities is 'Specified and Modeled'. This means that the requirements have been detailed and documented, and models have been created to represent them. This status is crucial for verification activities because it ensures that the requirements are clearly understood and can be systematically evaluated against quality standards to ensure they are usable for their intended purpose.
References: The BABOK Guide outlines that during the verification process, requirements should be evaluated against established criteria to ensure they are complete, consistent, feasible, and testable1. Additionally, the guide emphasizes the importance of having specified and modeled requirements as a starting point for verification activities2.
