Which modeling format is valid for use by the business analyst?

Diagrams are a valid modeling format for use by business analysts because they visually represent information, processes, and systems in a way that is easy to understand and analyze. Diagrams can illustrate relationships and hierarchies, process flows, data structures, and various scenarios. They help stakeholders grasp complex concepts quickly and facilitate communication among team members and other stakeholders.

Visual formats like diagrams can also enhance collaboration by providing a common reference point for discussions and decision-making. The structured nature of diagrams aids in identifying gaps, redundancies, or inefficiencies in processes. Consequently, they are a fundamental tool in the business analyst's toolkit for effectively capturing and conveying requirements.

While other formats, such as textual descriptions and non-linear graphics, may also have their place in business analysis, diagrams specifically cater to visual learners and leverage spatial awareness for better comprehension. Audio recordings, on the other hand, lack the clarity and visual representation necessary for modeling, making them less suitable for formal analysis purposes.
