A novel scheme for constructing product development portfolio based on TRIZ

“R & D efficiency” and “systematic management” are two major key issues concerned in this research. This paper considers how to apply TRIZ methods to improve product lifecycle management in enterprise, and establishes the contents of product development portfolio at the design stage. The proposed scheme is founded on the four pillars of TRIZ: Functionality, Resource, Contradiction and Ideality. We apply a relational structure containing four sectors of data representation to effectively record the contents of the product design. We also introduce 31 management parameters to product development process, and support R & D management and analytic mechanism. In addition, systematic management is planned to assist the relationships identification among design requirements, design parameters, and engineering parameters. Through the construction of TRIZ-based product portfolio we may easily trace engineering parameters related to significant quality factors and product improvement. The innovation cycle to gradually increase the “Ideality” of the product can be achieved.
