This study takes the steel wire manufacturer as the object and explores the customer’s view and evaluation of the service quality of the product providers. Varying from regularly seen methods for the quality evaluation of customer services, this study applies mainly the Kano Two-Dimensional Model and is supported with Importance-Performance Analysis (IPA) to explore the overall service quality of steel wires. This study takes the quality service phase of PZB as the foundation to design 20 items on the questionnaires which includes the basic steel wire physical properties and the wire services. To proceed the investigation by questionnaires, this study explores customer’s view about the current state of steel wires and analyses by IPA to find the key quality factor which should be improved immediately, and then categorizes the service items for steel wires by the feature of Kano Two-Dimension Model to find the property of each service item, and at the same time to calculate both the customer’s satisfaction index and dissatisfaction index for the quality of steel wire services. After the quality engineering technology being established, the relationship between the technology and the service items will be explored. The manufacturer of steel wires must integrate each relative quality engineering technology to build the priority items for the improvement, look for the target of improvements, make adequate plans for the limited enterprise resources, apply the improvement method and administration strategy for appropriate production businesses to proceed efficient quality improvements and the promotions, gradually achieve higher customer satisfaction step by step.
