Parametric Estimates

Postby nazrulq Tue Jul 25, 2017 7:44 pm

When Statistical relationship can not be used ( Rate per sq.ft) . Then 3 point with beta distribution is the best option! As scope is not fully defined.Parametric Estimate also Called Top Down Estimate.

Any Further suggestion will be highly appreciated!

According to Saket's Video Both Parametric and Analogous Estimates are Top Down Estimates. Analogus Estimates base on previous similar project while Parametric Estimates based on historical report or rate/sq.ft or linear
feet. I have seen anything in PMBOK refers Analogous Estimating is only Top Down Estimating approach but Rita's
Chapter (Cost) , Question no# 5 said Analogous Estimate as Top Down Estimates. I think in the Exam if both comes as an option then we have to go for Analogous Estimates as Top Down. Just Confirms Andy Crowre's explanation of Glossary said clearly Analogous Estimating is top Down.

Thank You.

Can Manish explain why only Analogous as both of the approaches are top down!
