What is a SIPOC?

A SIPOC is a high-level view of a process. It stands for Suppliers, Inputs, Process, Outputs, and Customers.

A SIPOC is ordered from start to finish. In conversational English, every Process starts with Suppliers, who provide Inputs to the Process, which results in an Output that is delivered to Customers.

Example of a SIPOC:
