Each time a schedule changes the mix of work or its timing, all workers and team leaders rethink their tasks, improve
them, and adapt them to the new conditions. Process improvement ideas that materialize at other times may be imple-
mented immediately, or bunched together and implemented at a schedule change.

Workers and team leaders identify and overcome their work problems using PDCA: Plan, Do, Check, Act. This deriva -
tive of the scientific method promotes kaizen based on facts, so the effort does not degenerate because people argue
contrary opinions. Writing the work instructions and holding to the methods they represent is the final "Act" stage of
PDCA improvement.

"Standard Work" refers to this entire process of routine grass roots kaizen. Once in operation, deviations from standard
work add greatly to process visibility ---- little light bulbs shining on problems for faster, tighter feedback. All TPS lead -
ers agree that standard work is the most time-consuming stage developing a new work culture.

Experienced workers don't need detailed instructions. Procedures common to a plant or department will be understood
and codified elsewhere. No form for recording work instructions is universal, but workers in a plant or location may
use a similar format.

Items to consider for regular workplace kaizen are shown below. Ohno himself originally listed the top three as mini -
mal requirements. 1
