The correct answer is C. Before the VM study begins . Customer information must be acquired during the Preparation Phase , also called the pre-study effort, because the VM facilitator needs accurate project knowledge before the formal study session starts. This includes the customer’s objectives, needs, constraints, priorities, budget concerns, schedule requirements, performance expectations, risk issues, and definition of success. Without this information, the VM team may begin the study with an unclear scope, incomplete data, or incorrect assumptions.

The customer’s input also helps the facilitator select the right team members, prepare the agenda, identify required documents, define study boundaries, and confirm the decision-making framework. By the time the team enters the Information Phase, the study should already be organized and supported by relevant background data.

Option A is weaker because waiting until the study begins reduces efficiency and may waste team time. Option B is incorrect because the final presentation is for communicating recommendations, not collecting basic customer requirements. Option D is incorrect because conceptual development occurs after functions and ideas have already been analyzed.
