Evaluation of product maturity based on quality characteristic

In order to understand the progress and fulfillment of product development promptly, an evaluation method for product maturity is proposed. At present, most study methods of product maturity are based on product readiness level from the perspective of management. The proposed evaluation framework of product maturity is to quantify the product´s inherent quality and reliability without considering the product readiness level. Firstly, the basic evaluation index system is established and for a specific product, Quality Function Deployment (QFD) would be used to build the evaluation index system based on the customer needs. Secondly, different evaluation methods are selected for different types of indexes. Thirdly, expert evaluation method or the back propagation neural network theory is used to decide the weights of indexes. Then with the evaluation values and weights of indexes, the comprehensive evaluation of product maturity would be obtained. Finally, the proposed method is demonstrated by a practical example.
