Part A:You have used the three-point method to estimate the duration of a task that you know will be critical to the project. The estimate produces a very large difference between the optimistic and pessimistic estimates. What actions, if any, might you take regarding the task? What are some of the reasons that estimating the duration of tasks can be so difficult? What strategies have you used or did you use in your project to overcome these difficulties?
Part B: Provide examples from your own experience of estimation techniques which have worked well on the projects you support or have supported in the past. What made them work well? What other techniques have you seen which did not provide an accurate estimation? Why did they fail?
