Universal Design Evaluation

Universal design evaluation appraises products, environments, and systems against the seven principles of universal design so that they are usable by the widest possible range of people without the need for adaptation or specialized design. The framework was codified in 1998 by Molly Follette Story, James Mueller, and Ronald Mace at the Center for Universal Design, who paired each principle with concrete guidelines and performance-measure checklists. Rather than retrofitting accommodations for a presumed average user, the method treats the full spectrum of human ability, age, size, and circumstance as the design target from the outset. Evaluation proceeds by specifying that user range, checking the design against the seven principles, observing diverse users in realistic tasks, and rating conformance principle by principle. The result is a prioritized set of design revisions that move a product toward inclusive, equitable use.
