Managing resource and technology interdependencies in project portfolio: A case-study results

In multi-project management, projects can not be taken in isolated way. They have often interdependencies with each-other, such as sharing human resources and modularized structure, and knowledge diffusion. Managing these relationships in portfolio selection and review process helps to make more effective selection choices and increase projects success rate in project portfolio management. There are many methods available to support interdependency management, but recent empirical findings show that not many of them are used in practice. In the present research, a multiple case study was performed to find out how interdependencies are managed in real life. The results show that interdependencies are mostly managed by informal ways. A description of managing interdependencies is given.
