Using Importance-Performance Analysis and Decision Making Trial and Evaluation Laboratory to Enhance Order-Winner Criteria ~ A Study of Computer Industry

Yu-Cheng Lee, Tieh-Min Yen and Chih-Hung Tsai
This study proposes a new decision analysis methodology that identifies the core order-winner criteria problems. A modified Importance-Performance Analysis (IPA) and multiple regression analysis are applied to define the implicit importance of quality characteristics and overall satisfaction. Gap analysis is used to identify the performance of quality characteristics. Decision making trial and evaluation laboratory (DEMATEL) is used to correlate the interrelationship among the quality characteristics. This methodology better defines the importance and priority over quality characteristic improvements and solves the practically complicated, contradictory problems with the least resources. This study performs empirical research into the Taiwanese computer industry and explains the application and benefits of the modified IPA and DEMATEL.
