When the project manager relies on consultants or the project team (or both), it is an example of expert judgment. Expert judgment is a technique based on a set of criteria that has been acquired in a specific knowledge area or product area. It is obtained when the project manager or project team requires specialized knowledge that they do not possess. Expert judgment involves people most familiar with the work of creating estimates.
