Prioritizing Customers Requirements in QFD by Integrating their Interrelationship with the Raw Weights

摘要

Quality Function Deployment (QFD) is a methodology used to achieve higher customer satisfaction. The Engineering Characteristics (EC) affecting the product, performance are designed to match the Customer Requirements (CR). Computing raw weights of CR and priority scores of EC from various input, variables is one of the most critical phases in QFD application. When EC priority score is calculated, ra w weights of CR and central matrix cell values are considered, while the impact of one CR over the other, ie, interrelationship among various CR is always ignored. Moreover, these CR interrelationships are neither mentioned nor factored-in the calculation. In this paper, an attempt has been made to address the issue by considering the impact of these interrelationships on the overall calculations, using weighted average method for the CR interrelationship value operator in order to prioritize customers' requirements in QFD. The proposed approach has been explained with an illustrative example.
