A SIPOC diagram identifies all elements of a process improvement project before work begins. It helps define the scope of a complex project by answering questions about where the process starts and ends, its major steps, inputs and outputs, key customers and suppliers, and customer requirements. The diagram provides a deep understanding of the current process. It typically includes suppliers, inputs, process steps, outputs, and customers. Metrics may also be included to define quality, time, and cost of inputs, processes, and outputs. The diagram helps scope and plan a process improvement project.

2. Purpose of a SIPOC Diagram
Identifies all elements of a Process Improvement Project
before work begins
Helps define and refine a complex project that might not be
well scoped
Helps answer questions such as:
Where does the process start and end?
What are the major steps in the process?
What are the primary process inputs and outputs?
Who are the key customers of the process (both internal and external)?
Who are the key suppliers of the process (both internal and external)?
What are the requirements of the customers?
Provides a deep understanding of the current process
