Overview

Bottom-up estimating involves the estimation of work at the lowest possible level of detail. These estimates are then aggregated in order to arrive at summary totals. By building detailed cost and time estimates for a work package, the probability of being able to meet the estimated amounts improves substantially.. Bottom-up estimates take more time to complete, but they also are more accurate than either analogous or parametric estimates.

Application

It can be used in any industries.

It has a motivating side, in that people feel involved and eventually they work to confirm their estimate.

Other Estimating Techniques

  • 3-points estimate
  • Parametric estimates
  • Analogous estimates
