The SIPOC is a simplification of a tool that author and quality guru, Philip Crosby called a Process Model. The Process Model had additional parts, but the center of the process model was in fact a SIPOC. For example, compare the steps in preparing a SIPOC with the "Xerox Quality Improvement Process" presented in Kearns, David T.; Nadler, David A. (1992). «Appendix 7». Prophets in the Dark: How Xerox Reinvented Itself and Beat Back the Japanese. New York: HarperCollins. s. 318. ISBN9780887305641. OCLC25283632.
