What is a SIPOC diagram?

A SIPOC diagram is indeed a tool that summarizes the inputs and outputs of a process, which is why this answer is the best choice. The acronym SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. This diagram is used to provide a high-level overview of a process, facilitating a clear understanding of the elements involved. By visually mapping out suppliers, the specific inputs they provide, the steps or activities of the process itself, the outputs produced, and the customers who receive these outputs, teams can identify key relationships and ensure clarity in process management.

This tool is particularly valuable in the Define phase of a Six Sigma project, as it helps teams to scope the project and ensures everyone has a common understanding of the process being analyzed. The clarity provided by a SIPOC diagram can assist in identifying areas for improvement and ensuring that key stakeholders are aligned throughout the project.
