%X In the Netherlands, a sharp increase in the number of infrastructure programmes occurred. The Schiphol Amsterdam-Almere infrastructure programme consists of five projects, of which four with Public Private-Partnerships contracts. This programme is one of the largest Dutch infrastructure programmes in history. Discovering how infrastructure programmes can effectively be managed can improve the effectiveness of future programmes. This paper therefore aims to contribute to more effective programme management. This is done through analysing programme management strategies and the underlying mechanisms behind their effectiveness. Nine semi-structured interviews with project- and programme managers in the SAA programme were conducted. This research found that a collection of strategies is utilised in order to effectively contribute to the overarching programme goals of accessibility and liveability. Effectiveness of strategies results especially from their collaborative effects. Thereby, outcomes are developed that allow for achieving the programme goals. Future programme managers can use insights gained on mechanisms behind strategy effectiveness to create effective PPP infrastructure programmes. %A Jochem (S.J.)
