sipoc definition and use
(January 2016) In process improvement, a SIPOC (sometimes COPIS) is a tool that summarizes the inputs and outputs of one or more processes in table form. The acronym SIPOC stands for suppliers, inputs, process, outputs, and customers which form the columns of the table. It was in use at least as early as the total quality management programs of the late 1980s and continues to be used today in Six Sigma, lean manufacturing, and business process management.
