Why information systems development projects are always late
Information systems development projects (ISD) are characterized by high rates of project overruns. To address this challenge, a novel explanation, which explores the effect on performance of task variance and task dependence, has been developed. The findings suggest that project overruns are a function of the interactive effect of the two variables driving both the level of, and variance in, project performance against schedule. To address this problem, this paper provides a number of suggestions for improving performance and also offers an explanation for why learning to improve performance in this domain has been slow.
