Certified Business Analysis Professional (CBAP) Practice Test

RACI Charts, while useful in defining roles and responsibilities in project management, do not serve as a valid technique for documenting requirements specifically. Their primary purpose is to clarify who is Responsible, Accountable, Consulted, and Informed regarding specific tasks or deliverables, rather than capturing detailed requirements about the system or project. In contrast, the other techniques mentioned are directly relevant to requirement documentation. Writing text requirements allows for detailed explanations and specifications of what is needed. Using matrix documentation helps in organizing and tracking relationships among requirements, often aiding in validating and verifying them. Graphical models provide visual representations of requirements, making complex information more accessible and understandable. Each of these methods contributes to a comprehensive understanding of requirements, while RACI Charts focus on team dynamics and not on the specifics of what the project needs to deliver.
