What is the purpose of a process map in Six Sigma?

The purpose of a process map in Six Sigma is to visualize and identify the steps in a process, which is crucial for improvement. By creating a clear and detailed graphical representation of a process, teams can better understand how each step contributes to the overall workflow, identify inefficiencies, and pinpoint areas where improvements can be made. This visualization allows for a comprehensive analysis of the process flow, leading to improved performance and reduced defects, which are key objectives in Six Sigma methodologies.

While other options address important aspects of business operations, they do not directly capture the essence of what a process map aims to achieve within the context of Six Sigma. Creating a graphical representation of customer needs, estimating product profit margins, or training employees on new procedures are valuable activities, but they do not specifically relate to the foundational role of a process map in identifying and improving workflow efficiencies.
