(A) Work breakdown structure
(B) Analogous estimating
(D) Bottom-up estimating
My selected option was #(C) , but the answer shows # (D). Problem in understanding.
If this question starts like : An estimating method where "Breaking down project activities into smaller components in order to obtain a more accurate cost estimate is called :" , then I would have definitely choosen the option#(D).
Any comment please.
Decomposition. A technique used for dividing and subdividing the project scope and project deliverables into smaller, more manageable parts.
Bottom-Up Estimating. A method of estimating project duration or cost by aggregating the estimates of the lower-level components of the work breakdown structure (WBS).
So process of estimation can be called bottom-up estimation but not the process of breaking activities into more estimatable activities.
The question talking about activities that already broken down from work packages to obtain accurate cost estimates is called Bottom-up.
The question not talking about breaking down the activities in to further.
