Definitive Estimates.


As per PMZilla Formulae page Definitive Estimates is : -5% to + 10%, but as per Rita Mulchay its -10% to +15% (pg 204).


What correct?

Good question.

 The problem is PMBOK does not give the range for definitive estimates. So some books have -5% to +10% while some have other figures.

 In exam, if you get this question, then most likely there will only be one of the two options.


The estimates that you have is near to the reality. It is simply one of the things that you can figure out for sure. - Marla Ahlgrimm
