These problems are increasingly occurring with an increase in varieties of and demand for the seats. Toyota currently addresses these problems offline; however, this is a deviation from the policies and procedures under the Toyota Production System (TPS). Now, as TMM ramps up for the production of the Camry Wagon, it must address the seat issue before seriously impacting production performance.

We recommend the following major measures to overcome these problems:


• Send TMM Quality Control (QC) people to KFS to identify and correct the source of the problem.

• Place a QC person at the seat arrival dock to check for defects before sending seats to the line.
