What is a common problem or waste in a process that has been brought out in our discussions and in several of the readings?
Imbalance in activities production rates
on a multistory tower, you have the workload staged for each floor. you have told all subs that they need to complete their tasks as quickly as possible because you are behind on the schedule. all of the subs speed up as directed devoting more people and time. however, the electricians speed up the most and gain an extra 2 days of production each week. the framing crew only gains about one day of production each week. in about 4 weeks, the electricians have come to a halt because they are waiting on the framing crew. how could this have been avoided?
Keep an even work flow and even out the workload
which one is not a principle discussed in "the toyota way"?
