The Project Definition Rating Index (PDRI) is a powerful and simple tool that offers a method to measure project scope definition for completeness. A PDRI score of 200 or less has been shown to greatly increase the probability of a successful project.
The PDRI offers a comprehensive checklist of 64 scope definition elements in an easy-to-use score sheet format. The PDRI score sheet is supported by detailed descriptions of these elements. Each element is also weighted based on its relative importance to the other elements. An individual, or team, can therefore evaluate the status of their project definition effort during pre-project planning and determine their score, or level of effort. Furthermore, since the PDRI element score relates to its risk, high risk areas that need further work can easily be isolated.
The PDRI can benefit owners, designers and constructors and provides numerous benefits to the project team. These include: a detailed checklist for work planning, standardized scope definition terminology, facilitation of risk assessment, assistance in progress monitoring, aid in communication of requirements between participants, method of reconciling differences between project participants, a training tool, and a benchmarking basis.
