The English acronym SIPOC denotes a Six Sigma tool for the define phase, which is also used in lean management .
purpose
A SIPOC diagram visualizes the snapshot of a process .
SIPOC can be used to record an overall process at the beginning of an improvement measure or an improvement project. In addition, SIPOC can also be used to clearly delimit processes in process chains. The output of one process becomes the input of another process.
Some authors recommend filling out the table from right to left to support a customer-centric view. In a brainstorming session , the content is often gathered without this limitation.
