The most astonishing result of my “Worst Waste Survey” (on the sidebar) so far is that out of 47 votes exactly 0 (zero) votes are for motion waste. This is an interesting contrast to a quote from Taichi Ohno in his book “Workplace Management”:
Why is it that many people do not perceive motion as major waste? I see the following reasons:
- Motion costs energy. What costs energy is perceived as work, and work is seen as value.
- Motion gives a feeling of business. For many people it is important to appear busy.
- Motion is ephemeral. Once it is performed it is gone, so you do not a lasting waste.
- Motion is positively loaded when you think about sports. Motion at work is not the same as sports performed in your free time.
From a Lean perspective it is different. Here are the reasons why motion is not work:
- Like transportation, is does not create results in itself, therefore not adding value. The fewer motion you need to perform a task, the better.
- Motion is also similar to over-processing. In many cases, the two go hand in hand. If you can so something in a more simple way you also reduce motion.
- In contrast to over-producing, motion does not create additional inventory waste. But it increases the time to perform a task, thus adding to waiting waste.
- No matter if in your job or at home, when you do something the goal should be to maximize added value. If you are a sports professional that includes motion, in all other cases not.
Having said that, I concur with the result of the vote:
Should the elimination of motion waste be post-poned until all other waste is gone? What do you think?
