Reblog: Art Smalley: Standardized Confusion » The #Lean Edge

Here’s a great piece of work from Art Smalley regarding the notion of “standards” at Toyota. Well, anything Art writes is good anyway, but this one unveils some confusion that might exist between the different concepts of “standards” and how and when each of them change.

May certainty help #PDCA and #Lean?

It occurred to me that uncertainty may hinder continuous improvement because it prevents action.

Consequently, people who are somewhat certain of their opinions are more willing to act and thus experiment and learn which are two root causes of improvement.

Of course, that implies that certain people are also willing to admit their errors when they act and things don’t happen as they expected. This is the purpose of Checking one’s actions and Adjusting if things went wrong (as in Shewhart/Deming‘s Plan-Do-Check-Adjust PDCA). (When things go well, it’s then time to turn the action into a new standard and diffuse it to whoever might benefit from it – in Lean, this is yokoten.)

Socrates said that you need to act to know if you’re right or not, for if you don’t act you’ll never know.

So, make up your mind, decide and act!

But always remember that you should be knowing just one thing: that you never know (until you act!)
