SIPOC is a method for identifying all relevant elements of a process.
SIPOC stands for the column names of the SIPOC diagram:
These can be internal and/or external suppliers or service providers for the process.
Materials, information, and all other input required for the process.
Describes the process steps required to create the output from the input. Five to seven steps are recommended for modeling at the macro level.
Describes the results of a process. Examples are products produced during the process, documents, or a service rendered.
Internal and external customers of a process, that is, both end customers and other processes.
The SIPOC diagram helps define a complex project that was not optimally planned.
It is usually employed in the DMAIC method phase during which a process is measured.
