1.       How many different estimating techniques were discussed in the case?

The different techniques of estimations discussed in this case are:

a)       Three-point estimates: In this technique, the project is classified into three sets of assumptions. These sets are optimistic estimate, pessimistic estimate and the no doubt estimate. As defined in terms of the duration of the project it is, optimistic time, pessimistic time and the most likely time.

b)      Three point estimating technique: In this technique an average of the optimistic, pessimistic and most likely estimate is used. This is generally utilized when the weights for the estimates cannot be determined.

c)       Analogy estimate: This the most common and easy to use technique as it uses past experiences to determine an estimate for new projects.

 

2.       If each estimate is different, how does a project manager decide that one estimate is better than the other?

Each and every project is unique and thus will use different estimates. Some might be complex and might require a higher skill from employees and more time, whereas some might be simpler which may be completed in a shorter time frame. Thus, it is very difficult for a project manager to decide which estimate is better as relative to another estimate.

 

3.       If you were the project manager, which estimate would you use?

I would use the analogy estimate as it is derived from past experiences and past similar projects. It provides some credibility to estimates instead of guess work. Barbara and Peter both have experience with such projects and according to their judgement, the project would require more time to be completed than provided by the estimates team. I would provide more weight to their judgement as they are personally involved with the tasks of the project and have experience to provide credible guesses as to the estimates of the project.
