A IDEF0-based methodology for project reliability assessment

This paper builds on an approach developed by the authors for extending IDEF0 modelling to act as a process reliability assessment tool. By quantifying the quality of the activity inputs the approach is able to assess the quality of activity outputs. The paper addresses how this approach is applied at a higher level to represent existing project management frameworks to improve their applicability. Two of these are PRINCE2 which is widely adopted in the UK and the second is PMBOK widely used in the USA. In this paper PRINCE2 is dealt with in detail while a recommendation for applying it to PMBOK is presented.
