Abstract: | The interdependence between projects in complex portfolios sharpens the challenge of project portfolio decision making. Methods that assist with the evaluation of data can address decision challenges such as information overload and time pressure. A decision simulation in a controlled experiment explored the use of visual representations of project interdependency data to support project portfolio decision making. Dependency matrices and network mapping were compared with non-graphical lists of dependency data. The findings show that the type of tool used may influence the quality of the resulting decision. Using visual tools, particularly network mapping displays, is correlated with the best results. |
