Zusammenfassung	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.	An accessibility audit is a systematic survey of a built environment that measures its features against accessibility standards or codes to identify, classify, and prioritize barriers facing disabled people. The auditor inspects elements along the chain of use—approach and parking, the entrance, internal circulation, sanitary facilities, signage, and controls—taking concrete measurements such as door clear widths, ramp gradients, and reach ranges. These measurements are checked against the criteria in the governing standard, and any element that falls outside the required range is recorded as a barrier. Barriers are then classified by severity and turned into a ranked remediation plan. Framed by the WHO International Classification of Functioning, Disability and Health, the audit treats the physical environment as an environmental factor that can either enable participation or, when it imposes barriers, produce disability.
