SIPOC Defined
• A SIPOC Diagram is a visual representation of a high-level process map; including suppliers & inputs into the process and outputs & customers of the process
• Visually communicates the scope of a project

• SIPOC Diagrams help a team and its sponsor(s) agree on project boundaries and scope
• A SIPOC helps teams verify that • inputs match outputs of upstream processes• outputs match inputs of downstream processes
How can SIPOC be used?
