Project portfolio management (PPM) is cnetral to many organisations' strategic processes and requires consideration of multiple factors and inputs and the ability to envision alternative future consequences to support strategic decision making. Complex project portfolios with multiple project interdependencies are characteristic of many project environments, yet existing methods and tools do not provide the clear understanding of project interdependencies that is required to support strategic project portfolio decision making. The exploratory research reported here introduces a new type of visual representaion and provides insights into the facots affecting an organisation's ability to understand prject interdependencies. Visual project mapping (VPM), the creation of graphical network displays of projects and their interdependencies, is shown to provide benefits by supporting communication and strategic portfolio decision making. The research also highlights the importance of the enivronment and the processes, and indicates that they both play an important role in an organisation's understanding of project portfolio interdependencies.
