What standardized work is
Standardized work is the documentation of the safest, most efficient, best-known way to perform a task, right now. It's the 6th of the 14 Toyota Production System principles, with an important nuance: the standard isn't a rule imposed from above, it's the best practice documented by the team itself.
The 3 elements
Takt Time
The pace needed to meet customer demand.
Work sequence
The exact order of steps an operator follows to complete the task.
Standard in-process stock
The minimum amount of material needed at the station for work to flow without interruption.
Without a known standard, there's no "improvement" — just change, and nobody knows if it made things better or worse.
Why it's the foundation of continuous improvement
You can only improve what's defined. If every operator does a task a different way, an improvement proposed by one of them isn't comparable to the others' starting point. Standardized work creates the stable baseline from which Kaizen can measure real gains.
