Abstract
Despite the growing number of organizations that have lost track of their application landscape and have suffered from a sharp increase in application portfolio complexity, a comprehensive and systematic approach to Application Portfolio Management (APM) still appears far from being adopted. To move the adoption process along, this paper develops a comprehensive framework assimilating and extending previous research and presents an APM process comprising data collection, analysis, decision-making, and optimization phases. This paper also presents an approach for evaluating software tools for APM and identifies which software tool families are best able to provide support for specific purposes. With this integrated conceptual guideline for APM and its translation into a model for measuring appropriate practical support, this paper not only allows for a move more deeply into the research area but also offers advice for both researchers and practitioners.
