Experts' estimates of task durations in software development projects - feb. 2000
This paper reports a case study of how accurate were experts' subjective estimates of the durations of tasks in a software project. The data available included the estimated task duration given by experts and the subsequent actual duraction times. By looking at the results of the case study, the paper shows that although the majority of tasks are overestimated, the mean error is an underestimate of about 1 . The experts however could do even better by taking more cognisance of the number of subtasks that make up a task and hence use the WBS at a lower level when they are estimating durations
