This chapter presents the results of research, which was conducted in an air systems manufacturing firm, located in the southwest of France: Liebherr Aerospace Toulouse (LTS). The purpose of the research was to elaborate and implement an appropriate project portfolio management (PPM) framework. PPM would link innovation strategic management and individual innovation project management. Individual innovation project management aims to manage each innovation project separately. In LTS, the team identified six types of what it decided to call “innovation project”: idea projects, technology development projects, prospect projects, proposal projects, product development projects and process development projects. The chapter presents an “innovation multi-project portfolio management framework” (IMPPM framework) that is elaborated from the new LTS's innovation management system. There are four innovation management vertical levels rungs from the lowest level to the highest: individual innovation project management, innovation project portfolio management, innovation multi-portfolio management and innovation strategic management.
