CAPM Practice: Determine how to gather requirements

Process flow diagrams (flowcharts, BPMN) visually represent business processes — showing activities, decision points, roles, and system interactions. They're powerful for capturing as-is processes and designing to-be processes that requirements must support.

**Why not B:** While data flow diagrams exist as a separate technique, process flow diagramming specifically models business process steps, decision points, and roles — not database data movement. Confusing process flows with data flows conflates two distinct modeling techniques used for different analytical purposes.

**Why not C:** Process flow diagramming documents business processes, not the business analyst's own workflow for gathering requirements. The technique is used to understand and improve how work gets done within the organization, not to describe the BA's personal methodology or elicitation approach.

**Why not D:** Process flow diagramming captures actual business operations, not project management procedures. Documenting PMO-approved project management processes is an organizational governance activity, not a requirements gathering technique used to understand how business work is performed.
