Replying to LO23020 --

On Wednesday, the 27th, Dan asked,

>In Deming's PDSA (Plan, Do, Study, Act) cycle, what distinction did Deming
>intend between "Do" and "Act?"

Dan, I was waiting to see if others responded, but since (apparently) not,
as I've always understood it, the "Do" component of the cycle meant to
test out the new / improved process or idea, generally in a "practice
field" of some sort where the rigorous "study" to follow could be carried
out. I learned this third stage as "check" [Shewhart, I think], meaning,
"what happened? did it work? how do we know?"

Then, the "Act" segment meant to modify the original new process or idea
on the basis of what was learned through Study/Check, and then and only
then implement the change in a more permanent way.

Is this how others learned this?
