I recommend not selecting what Process Map to do until you’ve done the walk. Here’s why:

  • What did you see?
  • How do you want to display that?
  • Are there a lot of hand-offs in the process and is that what you want to emphasize?

Then yes, a Swimlane Map is great. Is there a lot of wait time in the process? Then a Value-Stream Map may be better. What if excessive motion was discovered? Then a Spaghetti Chart is applicable.
