Devaux's Index of Project Performance (usually known as the DIPP) is a project management performance metric[1] formulated by Stephen Devaux as part of the total project control (TPC) approach to project and program value analysis. It is an index that integrates the three variables of a project (scope, time and cost) into a single value-based index where:
- Scope is monetized as the value the project is expected to generate if it is completed on a certain date;
- Time is a plus or minus monetary value if the completion is earlier or later than the target date; and
- Cost is the cost estimate-to-complete (Cost ETC) of the project, the monetary units that will be needed for resources to complete the project (i.e., factoring out sunk cost).
