Main findings were that: (1) most projects (60-80%) encounter effort and/or schedule overruns. The overruns, however, seem to be lower than the overruns reported by some consultancy companies. For example, Standish Group's "Chaos Report" describes an average cost overrun of 89%, which is much higher than the average overruns found in other surveys, i.e. 3040%.

(3) There is a lack of surveys including extensive analyses of the reasons for effort and schedule overruns.Read More
