The correct answer is C . BABOK says the purpose of Plan Business Analysis Approach is to define an appropriate method for conducting business analysis activities, and the Agile Extension explains that retrospectives are used for continuous improvement by reflecting on what went well, what could be improved, and how to improve the process. Because this initiative uses incremental monthly releases , the most appropriate first step is to review the latest retrospective from the previous release and use those learnings to select the approach for the next cycle. This is the strongest ECBA-aligned answer among the options.
Option A is incorrect because BABOK emphasizes selecting an approach that is appropriate to the current context , not simply reusing what worked at a different company. An approach must fit the initiative, stakeholders, and delivery environment.
Option B is weaker than C because team input can help, but the question asks for the first step , and the prior release retrospective provides concrete evidence from the same product and release model. In a monthly incremental environment, recent retrospective findings are more directly relevant than a general survey. This is an inference based on BABOK’s planning task and the Agile Extension’s use of retrospectives for continuous improvement.
Option D is incorrect because the scenario does not justify defaulting to a predictive approach. BABOK recognizes that the business analysis approach should be chosen based on context, and monthly incremental releases are typically more consistent with iterative or adaptive thinking than automatically choosing predictive just because the site is customer-facing.
