This Was Solved Once
In 1940, America taught plants how to train fast. Then it forgot.
When experienced workers were drafted in World War II, the government's Training Within Industry program taught supervisors a standard way to teach a job. It treated knowing the work and knowing how to teach it as two different skills.
By the final 1945 survey, every reporting plant had cut training time by at least 25%. After the war the US let the program fade. Toyota adopted it and still uses its job instruction method.
Fault Fixer applies the same idea to troubleshooting: a written, repeatable method instead of six months of shadowing.
