EXECUTIVE SUMMARY
Toyota Motors Manufacturing (TMM) faces increasing problems with its
seat supply. TMM’s single seat supplier, Kentucky Framed Seat (KFS), is
responsible for the majority of the problems with material flaws and missing
parts as the major encountered defects. 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:
Immediate
•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.
•Continue fixing seat defects off line. It is too expensive to stop the line.
