Bottom-up estimating approach
WebA well-known technique used when estimating projects is the bottom-up approach. If an activity’s duration or cost cannot be estimated with a reasonable degree of confidence, it can then be broken down to its different components. The individual estimates for these are then rolled up to calculate the overall estimate.
