Taiichi Ohno posted standard work sheets at every workstation, in the open, written by the operators themselves. He wasn't interested in whether people followed them. He was interested in how often…
If you walked onto a Toyota assembly line in the 1950s, you would've noticed something posted at every workstation, a sheet of paper hanging in the open where anyone could read it, the operator, the supervisor, a visitor from another company, a competitor.
On that sheet was the standard work for that station, the sequence of steps and the time each one should take, the exact amount of material that should be sitting there when the work began.
This is a company that has figured out the one right way to do the job and posted it so nobody deviates.
Frederick Taylor's stopwatch, Ford's assembly line, find the one best way, write it down, and make sure the worker never departs from it.
It was in how often it changed, because to him, a standard that had sat untouched for months was not a sign of a stable process.
The standard existed to be a baseline, the current best known way to do this job, held only until someone finds a better one.
And that distinction, it turns out, is the difference between an AI program that compounds and one that stalls.
