What a sipoc diagram is
A SIPOC captures a process at its boundaries: Suppliers, Inputs, Process, Outputs, Customers. It is the standard opening move of a Six Sigma Define phase, agreeing what is in scope before anyone starts measuring.
When to use one
- Starting a DMAIC project and scoping it with sponsors
- Onboarding a team onto an unfamiliar process quickly
- Settling a disagreement about where a process begins and ends
The data format
One item per line: S/I/P/O/C, item text.
Paste rows like this — copy the example straight into the builder to see it render:
S, Raw material vendor S, Logistics partner I, Steel coil I, Work order P, Cut to length P, Stamp & form O, Finished panel C, Assembly line C, OEM client
How to make one
- Paste your data into the Studio, or upload a CSV or XLSX file.
- Set your colours — by hand, from pasted brand hex codes, or extracted from your logo.
- Generate and export as PNG or SVG for your deck or report.
One thing people get wrong. Keep the P column to five to seven high-level steps. A SIPOC that becomes a detailed process map has stopped doing the scoping job it exists for.
Why it runs in your browser
Charts are parsed and drawn entirely on your own device. No rows, files or logos are uploaded, so a sipoc diagram built from confidential project or process data never touches a server. You can verify it: open your browser's network tab while you generate one.
