Process Mapping
Where the SIPOC is a linear flow of steps, process mapping is a means of displaying
the relationship between process steps and allows for the display of various aspects
of the process, including delays, decisions, measurements, and rework and decision
loops.
Process mapping builds on the SIPOC information by using standard symbols to
depict varying aspects of the processes flow linked together with lines with arrows
demonstrating the direction of flow.
