Abstract
A Technology Roadmap is a graphical representation of the development and relevance of markets, products, and technologies over time. The series of processes including formulation, preliminary preparation and post activities are referred to as Technology Roadmapping. This study examines the effectiveness of Technology Roadmapping for P2M based on a case study of a Japanese automotive parts manufacturer. As a result, it is assumed that the organizational infrastructure, which is essential for P2M, is developed through the process of preliminary preparation. It is also suggested that profiling management, program strategy management, architecture management, and platform management are promoted through the formulation process. In addition, it is considered that architecture management, value indicator management, life cycle management, and platform management are encouraged through the process of post activities.
