BAs use many techniques, such as:
-
Interviews → Asking stakeholders structured questions.
-
Workshops → Collaborative sessions.
-
Surveys/Questionnaires → Broad data collection.
-
SWOT Analysis → Identify strengths, weaknesses, opportunities, threats.
-
Use Cases/User Stories → Define requirements in context.
-
Process Modelling → Visualize workflows (e.g., BPMN diagrams).
Example: For a new HR system, a BA conducts interviews with HR staff and models the current recruitment process.
