This paper describes a functional framework that has been developed to realize a steady execution of a variety of complex projects. It provides knowledge to successfully intervene in a currently problematic situation. To achieve this, theory and practice have been equal constituents. The development is based on the Delft Systems Approach and the experience is gained from three executed projects at ship yards. The framework has been tested on project data and expert reviews, judging fit, relevance, workability and modifiability of the framework.@en
