Ringkasan	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.	Web accessibility evaluation assesses how well digital content conforms to the Web Content Accessibility Guidelines so that it can be used by people with a wide range of disabilities. WCAG 2.0, published as a W3C Recommendation in 2008 by Caldwell, Cooper, Reid, and Vanderheiden, organizes requirements under four principles—content must be Perceivable, Operable, Understandable, and Robust (POUR)—each broken into testable success criteria graded at conformance levels A, AA, and AAA. A rigorous evaluation combines three complementary methods: automated tools that scan for machine-detectable issues, manual expert inspection against the success criteria, and testing with assistive technologies such as screen readers and keyboard-only navigation. The evaluation determines whether the content satisfies all success criteria up to a target level and yields a conformance claim. Because no single method catches every barrier, the strength of the assessment lies in layering all three.
