What analysis method can clarify requirements by defining the necessary business terms?

The choice of a glossary as the analysis method for clarifying requirements by defining necessary business terms is appropriate because a glossary serves as a comprehensive collection of terms and their definitions relevant to a specific domain or project. By clearly delineating each term, a glossary helps ensure that all stakeholders have a common understanding of key concepts, reducing ambiguity and confusion. This is crucial in requirements analysis, where precise terminology is vital for effective communication and alignment among team members and stakeholders.

In contrast, concept modeling focuses on visualizing the relationships between concepts rather than solely defining terms. Functional decomposition breaks down high-level processes into smaller functions but does not explicitly define the terminology involved in those processes. Data flow diagrams represent the flow of information and the processes that transform that information, but they also do not concentrate on defining business terms. Each of these alternatives plays a valuable role in requirements analysis, but none match the specific function of a glossary in providing clarity around business terminology.
