Abstract The paper first examines some issues that hinder the effective management of, and decision-making on, quality software development process and products delivery by practitioners. It then generates a decision model for managing software development projects. The model uses four concepts: mappability, accountability, interoperability and controllability in decision-making which is assumed to be based on a set of indicators that link task status of the development process and its quality assessment to the responsible authorities. The quality of the tasks, and hence, of the deliverables is measured using four attributes: completeness, correctness, consistency and compliance. A web-based example implementation is then discussed. We thus show that the model is flexible, extensible and scalable. Implementation challenges and implications are then discussed.
