Main problem:
Toyota Motor Manufacturing, U.S.A. (TMM) is deviating from the standard assembly line principle of jidoka in an attempt to avoid expenses incurred from stopping the production line for seat quality defects. This deviation has contributed to the inability to identify the root cause of the problem, which has led to decreased run ratios on the line and an excess of defective automobiles in the overflow lot for multiple days. If this problem isn’t fixed quickly, an increased amount of waste will continue to be incurred and customer value will be threatened.
Analysis:
Friesen is truly struggling to find a way to "have his cake and eat it too". Friesen is passionate about TPS ways of achieving lean manufacturing by staying focused on achieving cost reduction by thoroughly eliminating waste. He knows that just in time (JIT) production is implemented to insure plants produce only what is needed, only how much is needed, and only when it is needed. He has been thoroughly trained in jidoka principles, understanding processes are put in place to make any production problem...

...ity to effectively get to the root cause of the problem and solve it for the long run.
Any short term gains achieved by not solving the problem on the line will not outweigh the long term gains that can be achieved by sticking to the tried and true TPS philosophies. Friesen needs to immediately cease the current deviation to the standards, and return to the proven jidoka and andon processes, which include implementing the "five whys" (see example, Appendix B), to truly uncover the root cause of the seat defects and find a long term solution.
