The creation of Six Sigma process maps depends on the complexity of the Six Sigma projects. Some process maps like the SIPOC (suppliers, inputs, process, outputs, and customers) diagram serve a specific purpose; in this case, it gives a brief outline of the business processes to the stakeholders. These high-level process map only outlines the process improvement initiatives and are used for stakeholders and executives.

  3. Organize and sequence process steps – After identifying all process steps, Lean Six Sigma specialists can organize the steps depending on the priority or sequence of the business processes.
  4. Use appropriate symbols to represent steps – Process mapping helps visualize; thus, appropriate symbols like rectangle, oval, arrow, diamond, and terminator must be used to describe process steps.
  5. Review the previous steps – Once the Six Sigma process map template is complete, it must be reviewed to check for omissions and mistakes.
