Analogous Estimating

Technique for estimating duration or cost using historical data from a similar activity or project.

Definition

It is top-down, quick, and inexpensive but less accurate, and is most reliable when prior work is similar in fact and estimators have expertise. It is common early when detail is limited.

Example

A previous similar website took 4 months, so the new one is estimated at 4 months.

Exam tip

Choose analogous when little detail is available early and a quick estimate is needed.
