Summary

SIPOC is a high-level process mapping tool used in Six Sigma and other process improvement methodologies to provide a clear overview of a business process.  The acronym stands for Suppliers, Inputs, Process, Outputs, and Customers.  SIPOC diagrams are typically created at the beginning of a process improvement initiative to help teams understand the scope and key elements of a process before diving into detailed analysis.

The SIPOC model begins by identifying the Suppliers who provide the necessary Inputs to the process.  The Process itself is then outlined in a few high-level steps, showing how inputs are transformed into Outputs.  Finally, the diagram identifies the Customers who receive the outputs.  This structured approach ensures that all critical components of a process are considered, helping teams align on what the process entails, who is involved, and what the desired outcomes are.

By using SIPOC, organizations can clarify process boundaries, avoid scope creep, and ensure that improvement efforts are focused and aligned with customer needs.  It also facilitates communication among stakeholders by providing a simple, visual representation of complex processes.
