Process Mapping is an established tool for the visualization
of processes. In comparison to process models of Business
Process Analysis, Process Mappings contain considerably
more details [12, 13]. A Process Mapping is a graphical
illustration that shows a sequence of activities using flowchart
symbols. A further objective of a Process Mapping is to
identify output variables (customer critical features) and input
variables (impact on critical features) of each process step.
Additionally, controllable factors (e.g. rotational speed) and
disturbance variables (e.g. vibrations) are also regarded [12].
Process Mapping is commonly used as a tool within the
Six Sigma methodology. In the DMAIC (Define-Measure-
Analyze-Improve-Control) circle it is applied as a process
visualization method within the Measure phase.
Process Mapping is a very valuable method for the
visualization of process flows taking into account the
aforementioned key figures. Yet, it does not cope with the
quality-related aspects of defect rates, inspection processes,
quality control loops or quality related costs.
