Purpose: The SIPOC Diagram is a high-level process map. This first step in addressing customer-related issues takes a process view of how our company goes about satisfying a particular customer requirement.
SIPOC stands for:
Suppliers – individuals or groups who provide whatever is worked on in the process
Inputs – information or material provided for that step
Process – steps used to do that work
Outputs – product, service or information being sent to the customer
Customers – next step in the process or the final (external) customers
Application: A SIPOC Diagram, a Process Map tool or both can be used during the Define Phase to scope the project.
- Helps us understand the relationship between customers, inputs, outputs and process steps
- Helps us understand how the process is measured
- Gives an overall glance at the process to help the team better scope the project
Purpose: Identifies all the steps in the process, lists key outputs, suppliers, customers and inputs at each step. Some maps may classify inputs and outputs as controllable, noise or standard.
Application: A SIPOC Diagram or Process Map should always be done at the first stages of an LSS project.
Provides valuable input to Cause & Effects matrix, Failure Modes Effects Analysis, Control Plan, Process Capability studies, Conducting Design of Experiments and understanding transactional processes.
