Question

Which estimating technique decomposes the work into lower, more detailed pieces, preferably the lowest level of WBS work elements, for which estimates are prepared and then aggregates them into a total quantity for the project?

Answer 1

Bottom-up estimating technique decomposes the work into lower, more detailed pieces.

Explanation:

Bottom-up estimating is the process of the estimation of work at the lowest possible level of detail. The estimates are accumulated to get the summary totals. The probability of achieving the estimated amount can be improved by building detailed cost and time estimates for a work package.

Bottom-up estimating is the project managing tool followed by many of the firms to estimate the cost and duration of project tasks. The bottom-up estimation consumes more time.
