The aim of this paper is to show how to apply TRIZ to resolve conflicts in management area, especially in product life management (PLM) in desinging and manfacturing smart-phone. TRIZ has been well-known as a creative and innovative thinking theory in solving engineering and technology contradictions in the last two decades. However, few studies and practical usage were proposed in management area. Conflicts occurring in product life management including schedule, budget, and risk ones at smart phone R&D process are discussed to demonstrate the ideas guided by 39 TRIZ management parameters, 40 TRIZ innovative principles, and contradiction matrix. The results show that TRIZ is able to provide direct, quick and effective alternatives to resolve the conflicts in PLM. In this manner, huge effort and cost can be saved in further project execution stage. In this paper, an innovative 3C consuming product such as smart-phone is utilized as a case study to describe the proposed TRIZ-based conflicts-solving approaches at PLM stage.
