What does a “SIPOC” diagram typically begin with?

A SIPOC diagram begins with a high-level overview of the process, which is the essence of what SIPOC represents. SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. This tool is often used in Six Sigma methodologies to provide a visual representation of the key elements of a process. Starting with a high-level view allows teams to outline the vital components of the process before delving into more detailed analyses.

This approach ensures clarity and alignment among team members and stakeholders regarding the process being analyzed. By establishing the broader picture at the outset, it enables participants to identify all necessary inputs and outputs without getting bogged down in the minutiae of detailed data initially. It sets a foundation for later stages of process improvement, where more specific analyses, such as cost or stakeholder impact, can be integrated.
