ABSTRACT: Nowadays, many product development projects fail as for not meeting customer’s expectations up to the mark as product development process is conducted very unsystematically and results in waste of resources. Customer requirement and satisfaction measurement is a major challenge which can be achieved through various methods. This paper presents joining methods of Analytic Hierarchy Process (AHP), Kano Model and Quality Function Deployment to improve the Tractor’s Seat design for tractor driver’s in Bangladesh in terms of ergonomic and user’s needs. A survey was done to 50 Tractor drivers to identify problems of the current seat. By analyzing the data identified the customer requirements and ranked it using AHP. With that Kano questionnaires were developed and answered by 50 tractor drivers. After that, with the integration of Kano model, QFD process was carried out to determine the customer requirement weight and the technical requirement weight to develop a modified design. At the end of the study, it was found out that both methods were able to prioritize the modification elements to be implemented into the new ergonomically designed tractor seat. Still there are some limitations. The analysis was performed based on 50 tractor drivers. For more correct results, more than 50 drivers could be taken into account.
