You want a form of expert judgment, but the sponsor argues for analogous estimating. Analogous Estimating: based on previous activity of similar nature (a form of expert judgement), used when little is known or very similar scope, works well when project is small, NOT ACCURATE; Parametric Estimating: based on some parameters, e.g. As a project manager one of the most important thoughts at project start-up is the reliability of the estimates. No calculations. One is meant for money to spend and the other is meant for the time taken . Estimating? I am also studying for the exam and was hit or miss on questions when both types of estimating techniques were present as one of the answers. Analogous estimating uses an “analogy” – comparing a past similar project to your current project. All in all, parametric estimating tends to Analogous Estimating is top-down estimating method.
