What the operating system changes
These habits help people spot missing information, wasted movement, and quality problems sooner.
The people closest to a process are encouraged to identify waste, clarify handoffs, and build a better method.
Finding a problem early gives the team a chance to correct the work and strengthen the process.
A successful method becomes a standard so the next part does not depend on memory.
Requirements, checks, and workmanship reviews happen during the work, not only at the end.
