Firm performance required numerous projects like total quality, reengineering of innovation and knowledge processes, rationalization projects. Their respective results and impacts are assessed through performance models or frameworks which are rarely combined although managers could benefit from integrated and coherent models, mainly for innovation and KM (Knowledge Management). Models for measuring innovation and KM performance are new and concern mainly large companies. They have almost all been developed relying on input/output frameworks. The processes generating performance are not thoroughly taking in account. Drawing upon a literature review and a theoretical study, this paper contribution is based on an integrated conceptual model combining the value innovation chain of Hansen and Birkinshaw (2007) [1], and the SECI KM model of Nonaka and Takeuchi (1995) [2], to build an integrated KM-innovation framework which can help to assess KM projects and innovation projects in different types of organizations.
