Companies increasingly support their project portfolio management processes with specific software, and the market for IT solutions is growing. While project portfolio management information systems (PPMIS) promise to improve the quality of the management process and eventually portfolio performance, it is unclear whether they actually deliver on this promise. We lack empirical evidence regarding the actual benefits of PPMIS and knowledge on the conditions under which PPMIS application is most beneficial. Using a sample of 181 project portfolios, this study shows for the first time that PPMIS application is overall positively associated with the quality of portfolio management processes and project portfolio success. However, moderation analyses further reveal that these effects only materialize when formalization of single project management, project portfolio management, and risk management are sufficiently high. Surprisingly, the benefits of PPMIS application do not depend on portfolio complexity (size, project interdependency, dynamics).
