SIPOC+CM Diagram Offers High-Level View of "As Is" State of a Process Under Investigation

Related Categories: Quality Improvement


The SIPOC+CM Diagram, originally published in The Public Health Quality Improvement Handbook, has been featured on the American Society for Quality website.


SIPOC+CM is a data collection form that assists in gathering information about Suppliers, Inputs, Processes, Outputs, and Customers of a process. It is used before constructing a flowchart and creates a high-level view of the "as is" state of a process under investigation. This tool adds additional categories: Constraints facing the system and Measures to be used.


When a team needs a way to record collective knowledge about a process in a user-friendly format, the diagram can help to define the process boundaries so that everyone involved understands the limits of the analysis. A variation of this tool, the SIPOC+CM Collection Form, is also included in the 2012 Public Health Quality Improvement Encyclopedia.
