On the slide where it says that the plot is DMAIC – if it is only a Kaizen event, what would be an ideal plot?

Kaizens follow the same path. You still have to define the issue, measure the baseline, analyze the process and the data in order to brainstorm solutions. It’s just a 2-5 day operation. You could use PDCA (Plan Do Check Adjust) as well. That also follows the Scientific Method. It just puts DMA into the “Plan” step.
