What is a SIPOC diagram and when is it constructed?

SIPOC maps Suppliers, Inputs, Process (5 to 7 high-level steps), Outputs, and Customers. It is drafted at the beginning of the Define phase to establish boundary conditions before detailed value stream mapping or process flow charting.
Process Flow: Suppliers → Inputs → High-Level Process Steps → Outputs → Customers

High-Level Boundary Mapping for DMAIC Define
