Although project portfolio management (PPM) has been on the research agenda for at least seven decades (1950–2019), the number of contributions on the topic continues to grow. Literature reviews help us to integrate and build on what we already know and to understand where we came from. However, reviews proving a shared historical narrative of the discipline are scarce but key. Thus, we trace the literature back to its origin, building and synthesizing our historical narrative into a model. We evaluate what has already happened and what will most likely shape the future.
