Abstract: Adequately considering project interdependencies has shown to be a determinant of how successful IT/IS project portfolios are managed. However, this can be especially troublesome since there is no universal way to handle many project interdependencies that continue to change over time due to environmental uncertainty or unexpected decisions. This can seriously disrupt portfolio performance. In this article, the authors used the systems perspective to address the problem of managing multiple IT-project interdependencies in complex IT/IS portfolio environment. In particular, the authors propose using the cybernetic model Viable System Model to facilitate thinking and reasoning concerning the difficulty of managing IT-project interdependencies. To validate their approach and to ensure the appropriateness of it, the authors used real-world problem situations drawn from multiple case studies conducted in four leading organizations in Saudi Arabia. The findings support that the Viable System Model can be applied to assist in diagnosing and handling of IT-project interdependencies.
