A process map is a graphical depiction of a process, set in a way that allows the workings to be shown. Before constructing a process map, team members should agree on the meaning of the symbols to be used and the scope.
- Easy to use
- Provides a high-level, visual depiction of critical elements and handoffs
- Useful as a training aid
How to Use
- Step 1. Determine the scope of the process to be defined.
- Step 2. Draw a “start” step for the process.
- Step 3. Observe all of the steps in the process.
- Step 4. Draw a symbol for each step.
- Step 5. Verify that the finished process map accurately portrays the steps in the process.
The example below shows a process map for a distribution warehouse:
- Arrows show the direction of material flow
- Diamonds show a process where decisions are made
- The square shows a process where work is done
- Circles are the “begin” and “end” steps
