This document introduces the return on investment (ROI) methodology for measuring the value of project management. It discusses why measuring value is important, as most projects are over budget and behind schedule. The ROI methodology provides a 10-step process for conducting an evaluation, including planning objectives, collecting data during and after implementation, analyzing data, calculating costs and benefits, and reporting results. Implementing ROI can help justify budgets, improve processes, and show how project management contributes to business goals.
