Exam CAPM topic 1 question 176 discussion

Why the other options are incorrect: A. Early requirements gathering: Happens at the start of the project. In this case, the refinement is happening after prototyping. B. Feedback analysis: Is a general term and could be part of the process, but it’s not the recognized project management technique being described. D. Requirements documentation: Refers to the process of formally recording requirements, not refining them through testing and iteration.

C. Progressive elaboration The team is using the technique of "progressive elaboration." Progressive elaboration is a project management technique that involves continuously refining and expanding project details and requirements as more information becomes available throughout the project's lifecycle. In this scenario, the team initially created a prototype of the drone and sent it to the customer for testing. Based on the feedback received from the customer, the team used that information to refine and expand the project requirements. This iterative process of refining and expanding project details is an example of progressive elaboration, which is commonly used in agile and adaptive project management approaches to accommodate changing customer needs and project insights.
