SIPOC Diagram Builder – Online Supplier Input Process Output Chart

A SIPOC diagram is a visual tool that summarizes the key elements of a business process: Suppliers (who provides inputs), Inputs (resources needed), Process (the steps to transform inputs), Outputs (results produced), and Customers (who receives the outputs). It's widely used in Six Sigma DMAIC projects to establish process scope and identify stakeholders before detailed mapping begins. SIPOC helps teams align on process boundaries and uncover improvement opportunities quickly.

Start with the Process column — list 4–7 high-level steps that describe the core workflow (e.g., "Receive order → Verify payment → Package item → Ship"). Then identify Outputs (what each step produces) and Customers (who receives them). Next, work backward to define Inputs (what each step requires) and Suppliers (who provides those inputs). Use this builder's editable cells to type directly into each column — add rows for additional items as your process grows in complexity.

A SIPOC provides a high-level, bird's-eye view of a process and its ecosystem (suppliers and customers), typically captured on a single page. A flowchart (or process map) dives deeper into individual steps, decision points, and detailed workflows. SIPOC is often created before detailed flowcharts to set scope and context. Use SIPOC first to align stakeholders, then use flowcharts for granular analysis and improvement.

Best practice recommends 4 to 7 high-level process steps. Too few steps lose meaningful detail; too many steps turn the SIPOC into a detailed process map, defeating its purpose as a scoping tool. Each step should represent a distinct phase of the process, described with a clear verb-noun format (e.g., "Collect customer requirements" rather than just "Requirements").

Yes! Use the Print / PDF button to print your SIPOC chart or save it as a PDF via your browser's print dialog. The Copy Text button copies all data as tab-separated text, which you can paste directly into Excel, Google Sheets, or any spreadsheet application for further formatting. Your data is also automatically saved in your browser, so you won't lose your work if you refresh the page.

SIPOC diagrams are used across virtually all industries: manufacturing (production line analysis), healthcare (patient journey mapping), IT & software (service delivery processes), finance (loan processing), logistics (supply chain mapping), and service industries (customer experience design). Any organization looking to improve process efficiency can benefit from SIPOC mapping.
