The measure of meaningful standard work charts comes down to the level of details. Details spell out exactly "How" to perform the process method without question. Any operator should be able to follow the instructions and successfully perform the work steps.
According to author Jeffrey Liker in his book The Toyota Way, standard work at Toyota is detailed to the footstep. His example was 28 steps for a 44.7 second job. That's one documented step for every 1.6 seconds of work including the number of footsteps for each element. With this level of meticulous documentation, I can see how Toyota can effectively establish a consistent standard work process.
Based on this comparison, our standard work charts have plenty of room for continuous improvement.
