Abstract: Right First Time (RFT) is one of the internal business measure to ensure the quality of the product. This project deals with the elimination of wrapper fouling with bumper issue in MF 9500 Models. The wrapper is A class part which is assemble in front of tractors which when getting damage will lead to customer dissatisfaction. The wrapper damage at field results in customer / warranty claims thus increasing the external cost to the company. The wrapper damage issue is due to fouling issue in tractors and that issue is taken up for this study.. Initially PFMEA study conducted for wrapper assembly process. Further based on PFMEA results, a systematic analysis is done through cause and effect diagram to identify the other causes for wrapper damage issue. Since the cause and effect analysis not able to reveal the real root causes. Two models is proposed with modification and performance of the model is studied and compared. It is observed that proposed models are capable of reducing the wrapper damage considerably. It is also noted that modification in the proposed model reduces the operator inspection time and fatigue.
