Regarding project management, many organizations have developed and distributed general project management knowledge systems, and application fields use the knowledge systems to apply the process suitable for characteristics of a project. This study suggests project management process models to apply to product development projects and introduces the application cases. This product development project management process model is composed of five top processes of initiation and preparation, planning, implementation management, control, and termination and transfer. The five processes are re-divided into 18 bottom processes. These processes are expressed as input, control, output, and mechanism by using the IDEF0 model. This model is applied to the new car development project of a Korean automobile company and introduces the cases, which shows a project charter, a work breakdown structure, a project schedule, a progress s-curve, a risk register, and a performance report.
