Bottom Up Estimating Definition

Bottom Up Estimating Explanation

A number of techniques can be used to estimate costs and activities durations after the project activities are defined. These estimates are used to develop schedule and budget of the project. One of the techniques is called bottom-up estimating. As the name indicates, bottom-up estimating uses the lowest level activities in the work breakdown structure to estimate cost or duration. When an estimate for a particular activity cannot be made, the activity is further decomposed and the estimates for the detailed tasks are made. These estimates are then combined together to get the estimate of the activity.
