This document summarizes the key findings of the Standish Group's research on software project failures. Some of the main points include:
- 31.1% of software projects are cancelled before completion and 52.7% exceed their original time and budget estimates. On average, cost overruns are 189% of the original estimate.
- Only 16.2% of projects are successful, meaning they are completed on time, on budget, and with all specified features. The success rate is even lower for large companies at only 9%.
- Common reasons for failures include changing requirements, lack of user involvement, lack of management support, and unrealistic expectations. Restarts are also a major cause of cost and time over
