What is a SIPOC Diagram?
SIPOC stands for Suppliers, Inputs, Process, Outputs, and Customers. It's a high-level process mapping tool used by BPM consultants, Six Sigma practitioners, and process analysts to understand the scope and boundaries of a process before diving into detailed mapping.
A SIPOC diagram answers five fundamental questions:
- Suppliers — Who provides the inputs to this process?
- Inputs — What materials, information, or resources enter the process?
- Process — What are the 5-8 high-level steps?
- Outputs — What does this process produce?
- Customers — Who receives the outputs?
When to Use a SIPOC
- Before a process elicitation session — to scope the conversation
- At the beginning of a Six Sigma project — to define process boundaries
- When onboarding new team members — to give them a high-level overview
- During process audits — to verify that all stakeholders are identified
How to Create a SIPOC in 5 Steps
- Start with the Process — Define 5-8 high-level steps using verb + noun format ("Receive request", "Review budget", "Approve order")
- Identify Outputs — What does each step produce?
- Identify Customers — Who receives each output?
- Identify Inputs — What does the process need to start?
- Identify Suppliers — Who provides each input?
Common Mistakes
- Making the process steps too detailed (keep it to 5-8 high-level steps)
- Confusing internal handoffs with suppliers/customers
- Forgetting to include system inputs (data, templates, policies)
