We’ve talked about Pareto Charts before. They are a lot of fun. Really. I mean it. But I was recently introduced to a new tool, and couldn’t wait to share it.
When you are living in a Lean world, part of your job is looking at certain metrics every day. When one of your metrics goes off the rails, it becomes the leader’s job to determine what is causing the defect and define the corrective action. The living Pareto chart will help you do that in real time. Let’s take a closer look:
Count of incident is on the left side. Reasons for defect are on the bottom. Dates in the grid are a list of each time that particular incident occurred. Stuck on your Gemba board, this allows you to get good data at the point of failure each time. But even more important is that red line. That line is the upper control limit. If the number of incidents cross that line, it’s time to take action.
From there you have your choice of tools, of course. Five Whys, Fishbone, FEMA, or plenty of others. It doesn’t really matter which one you use. But this tool lets you track how often you have a defect, what caused the defect, and tells you when it is time to act. I love it. And I couldn’t wait to share.
Give it a shot. You’ll love it, too.
