KEY ISSUES / PROBLEM STATEMENT Toyota Motor Manufacturing USA, Inc., (TMM) is confronted with its rising problem with seat supply and one of the main culprits is the seat defects. Reflected in the decreasing run ratio; as a result there is a growing number of cars sitting off-line with defective seats or no seats at all requiring overtime to make up for the loss production.

SUPPORTING ARGUMENT The seat supply problem is the major issue because it constricts the company to supply the cars on time to the sales company. The seat problem resulted with a ten point drop on the run ratio from around 95% down to a meager of 85%.

There are 18 vehicles found at the parking area having defects in seats which have an equivalent potential loss in sales with $ 679,320 per annum, based on the 17% pretax profit.
