What is the MAIN purpose of value stream mapping in an organization?

The main purpose of value stream mapping is to identify and prioritize improvement opportunities, which makes option B correct. ITIL presents value stream mapping as a practical way to understand how work actually flows across teams, systems, and organizational boundaries. By visualizing the “as-is” situation, organizations can spot bottlenecks, delays, handoff issues, waste, duplicated effort, and points where value is lost or slowed. This analysis helps them decide where improvements will have the greatest effect. Mapping may also support better collaboration and management practice use, but those are secondary outcomes. It is not mainly about automating monitoring or controlling stakeholders. The real value lies in making the flow of work visible so that improvement efforts can be based on evidence rather than assumptions or isolated local viewpoints.
