(1) A type of flowchart depicting the steps in a process and identifying responsibility for each step and key measures.
(2) A work flow diagram which depicts the elements of a work flow often using time, people, and machine information to illustrate tasks and results.
(3) A visual representation of the workflow either within a process - or an image of the whole operation. One differentiates between "30,000 feet overviews", "Medium image" or "homing in", "zooming in", "Micro Map" &c. A good Process Map should allow people unfamiliar with the process to understand the interaction of causes during the workflow. A good Process Map should contain additional information relating to the Six Sigma project i.e. information per critical step about input and output variables, time, cost, DPU value.
