What analysis method is focused on business rules to specify and model requirements?

Business Rules Analysis is the correct choice because it specifically concentrates on identifying, articulating, and managing business rules that govern an organization’s operations. This method provides a structured way to capture the rules that dictate how business processes should function, ensuring that all requirements are aligned with organizational policies and regulations. Through this analysis, business analysts can create a clear representation of requirements that are derived from these rules, leading to a better understanding of what needs to be implemented in the systems being developed.

In contrast, Concept Modeling primarily focuses on capturing the relationships and ideas that define business concepts, without the specific emphasis on operational rules. Data Modeling is concerned with structuring and organizing data to support business functions, while Functional Decomposition breaks down complex processes into simpler, manageable components. Although these methods can contribute to understanding requirements, they do not emphasize business rules in the same way that Business Rules Analysis does.
