Find the task Duration

Imagine that you are a project manager. How would you begin to estimate the time that a project would take to complete? Given a small or simple project, this task may not seem too daunting; however, for a large, complex project, such as the construction of a high-rise building, the task of estimating time for project completion is a difficult one.

Briefly describe the six methods for estimating task duration. Discuss how each method affects the accuracy of task duration estimates. Provide practical examples to help illustrate the differences between the methods. How do you determine which method should be applied to a particular facet of a project?
