The correct answer is A because value stream mapping is not only an analytical technique; it is also a powerful cultural intervention. By bringing stakeholders together to visualize the end-to-end flow of work, it creates a common understanding of how the system really operates. This matters because different teams often see only their own part of the process and may blame other groups for delays, defects, or friction.
A shared value stream map helps replace opinion, defensiveness, and silo thinking with evidence-based discussion. It allows development, operations, security, testing, business, product, release, and support stakeholders to see the same constraints, queues, dependencies, and waste. That shared visibility can jump start cultural change because teams begin to understand that the problem is usually in the system of work, not in individual effort.
Automated metrics collection may support later improvement, but it is not the cultural effect being tested. Vendor selection is unrelated. Moving to a product-centric model may be an eventual outcome, but the immediate jump start is shared understanding and cultural alignment.
