Abstract: Aiming at the deficiency of traditional software design and development in considering product innovation and the innovation preferences of customers,an identification and prioritization method of feature-oriented software product innovation opportunities was proposed to improve the customer satisfaction and the project delivery success rate.The interval-valued 2-tuple linguistic,QFD and DEMATEL were employed to translate the customer requirements and their importance degrees into software features and their importance degrees.Based on the customers' innovation preferences analyzed by Innovative Kano (I-Kano) model,the innovation variation methods of multi-dimensional technological innovation map were applied to identify innovation opportunities of software features,and the satisfaction of innovation opportunities was quantified.To prioritize the proposed innovation opportunities,an ISC-Dim three-dimensional evaluation model composed of the importance of software feature,the satisfaction and the cost of innovation opportunity was established.An example of innovative design and development for a work value management system was given to demonstrate the feasibility and validity of the proposed approach.
