Requirements scrubbing

Requirements Scrubbing is a practice in which a product specification is carefully examined for unnecessary or overly complex requirements, which are then removed.

Since product size is the largest contributor to a project’s cost and duration, reducing the size of the product produces a commensurately less expensive project and shorter schedule.

Requirements Scrubbing can be used on virtually any project and any company.
