Analogous Estimating
Analogous is an estimating technique that uses the values of parameter, such as scope, cost, budget, and duration or measures of scale such as size, weight, and complexity from a previous, similar activity as the basis for estimation of the same parameter for a future activity. It is a top-down estimating technique and is a form of expert judgment. It provides a lower degree of accuracy than other estimating techniques. This technique is primarily used when there is a limited amount of detailed information about the project or program.
