(Which technique can be used to understand roles and responsibilities within an enterprise, facilitate engagement...

The correct answer is A. BABOK identifies Organizational Modelling as a technique used to understand the roles, responsibilities, and communications within an organization. It is also referenced in Plan Business Analysis Governance to help define a governance approach involving the appropriate stakeholders and decision-makers, which directly supports engagement and approvals.

Option B is incorrect because SWOT analysis is used to examine strengths, weaknesses, opportunities, and threats, not to map organizational roles and approval responsibilities.

Option C is incorrect because Benchmarking compares performance or practices with others, but it does not primarily identify internal roles, responsibilities, or decision-makers.

Option D is incorrect because Market analysis focuses on external market conditions and trends, not internal enterprise roles and governance relationships.
