The debriefs are a time for the team to share and communicate what they saw. During the walk, the process walkers are learning and listening. During the debriefs, the process walkers are sharing and comparing what they’ve learned. It’s a great way to process what people saw. You don’t need a current state process map to discuss what you saw. There are plenty of observations and A-HAs. These debriefs occur between interviews (a debrief should occur after approximately 3 interviews so that walkers won’t forget observations, A-HAs, and/or quick hit opportunities). Discussing and debriefing the interviews as a group is a great way to compare and contrast what the walkers are seeing and confirm that they’re all seeing the same process.
