It Has to be Accurate
Is the accuracy requirement a third rule or built into rule 1? Either way, here are two of the most common pitfalls to process-mapping accuracy.
1) Going from memory:
By now you’ve read about going to the gemba. Process detail and nuance can be discovered there. Of course, the gemba is rarely amenable to a process mapping session. Start in the conference room (with the front line experts who do the work) and then verify by revisiting the gemba or asking additional process owners to review your work.
2) Mapping the “sposda state”:
Sposda is insidious because it poses as the current state. When mapping the current state, it never hurts to remind your team (and yourself) that the intent is to map the process as it actually happens, not the way it is supposed to happen. This may feel like airing dirty laundry and thus it’s tempting to map the sposda state. Help your team past this.
