SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. It is a one-page framework for defining a business process end to end: who feeds it, what goes in, what happens inside it, what comes out, and who receives it.
A SIPOC diagram is the fastest way to pull a fuzzy process into focus. You draw five columns, fill them in, and suddenly the hidden dependencies, missing handoffs, and unclear ownership are on the page where you can fix them. It is the default starting point for most Six Sigma, Lean, and business process management work, and it has become even more useful in the AI era, where you cannot hand a process to an agent until the inputs, outputs, and boundaries are spelled out explicitly.
