Abstract: To solve the difficult problem of measuring customer contribution for product innovation or tasks directly,the product innovation work was decomposed into tasks,sub-tasks and smallest task units based on work breakdown structure.On this basis,an approach to measure customer contribution for activity was proposed.A task importance evaluation method by integrating fuzzy extended analytical hierarchy process and data envelope analysis was put forward to determine task importance quickly when the number of tasks was large.The contribution of customer for product innovation and tasks was determined by combining customer contribution for activities and the importance of activities and tasks.The application process and feasibility of the proposed approaches was demonstrated by an illustrated example.

Key words: product innovation, customer contribution, work breakdown structure, fuzzy extended analytical hierarchy process, data envelope analysis
