What is it, and why use it?
SIPOC stands for Suppliers, Inputs, Process, Outputs and Customers. It is a concise overview of what enters a process, the broad activities, what leaves it and who receives the result.
It gives the team a shared scope and prevents a project from quietly expanding to unrelated work.
Explore the SIPOC features and local-file workflowWhen to use it
Use it early, especially when several departments disagree about where a process starts or ends.
When another tool fits better
Use a flowchart for individual decisions and loops. Use CTQC to turn a customer expectation into a detailed measure.
Before you start
- The event that starts work and the output that ends it.
- Representatives of upstream suppliers and downstream customers.
- A small number of broad process stages.
Use fictional or approved non-sensitive information. Do not include patient details or proprietary records in practice worksheets.
Step-by-step in CI Tools
State the process purpose and agree its start and end with the team.
Complete the Suppliers and Inputs lists: pair each important input with its source.
Add high-level Process steps in order; use the move controls to correct the sequence.
Complete Outputs and Customers, including internal recipients who depend on the result.
Review missing inputs and outputs with the people involved, then create a detailed flowchart only where needed.
Agree boundaries before adding detail
Use an observable trigger as the start and a received output as the end. If participants use different boundaries, reconcile those differences before comparing measures or redesigning handoffs.
Completed worked examples
Demonstrations only: all organizations, observations, targets and results below are fictional. They are not clinical instructions or universal performance standards.
Healthcare operations — fictional
Equipment preparation
Starting information: A fictional outpatient unit prepares clean equipment for scheduled rooms.
| Suppliers / inputs | Central stores / approved equipment list and cleaned devices |
|---|---|
| Process | Request → Prepare → Check → Deliver |
| Outputs / customers | Checked equipment kit / room team |
What the result means: The boundary ends when the kit is handed over, not after the appointment. Clinical procedures are outside this operational example.
General business — fictional
Purchase-order creation
Starting information: A fictional office turns an approved request into a purchase order.
| Suppliers / inputs | Requester / approved need and budget code |
|---|---|
| Process | Validate → Select supplier → Create → Authorize |
| Outputs / customers | Authorized purchase order / supplier and accounts team |
What the result means: The accounts team is also a customer because it needs a usable order reference. Payment processing can be a separate process.
Practise in a separate worksheet
Open the tool’s built-in synthetic sample as a new editable worksheet. It may differ from the worked demonstrations above. It never replaces an existing worksheet. Save any work you want to retain to your computer.

Common mistakes and how to avoid them
- Listing every mouse click: keep SIPOC high-level and move detail into a flowchart.
- Leaving out internal customers: include anyone who relies on an output.
- Using department names as process steps: name the activity rather than only the team.
Interpret the result
The output is an agreed scope, not a performance score. Check whether every output has a recipient and every critical input has a source. Use gaps to guide interviews and data collection.
Record the assumptions and unanswered questions alongside the result. Use the relevant local review process before making operational decisions.
