Job Methods is the TWI module focusing on improving the workplace. The method is a basic four-step process focused on optimizing mechanical work. The underlying approach is good. The documents from 1945, however, put the improvement squarely on the shoulders of the supervisor.
My belief is that the workers should be involved much earlier and that the decision of what to improve would also benefit from more attention. But the basic method is still sound. The TWI people also saw this problem, but their management told them that it is “good enough.” Hence this module saw a lot of improvements after 1945. Yet, it was the smallest of the three main programs. Let me show you the TWI Job Methods in more details. This is the fourth in a series of five posts on TWI.
