What Lean Six Sigma tool assists practitioners in defining their specific processes?

A process map is an essential Lean Six Sigma tool that provides a visual representation of a process, illustrating the sequence of steps involved in that process. It helps practitioners to clearly define and understand how a specific process operates, including inputs, outputs, and the interactions between different steps. By mapping out a process, teams can identify areas for improvement, waste, and inefficiencies more effectively.

In contrast, other options serve different purposes. A general business policy manual outlines company policies and procedures but does not specifically focus on process mapping. Takt Time analysis is used to balance production with customer demand, while the 5 Whys technique is a problem-solving tool aimed at identifying the root cause of an issue. While these tools are valuable in their own contexts, they do not directly assist in defining specific processes as effectively as a process map does.
