Scenario-Based Evaluation

An accessibility evaluation approach that assesses the complete user experience across a sequence of steps needed to accomplish a task, rather than testing individual pages in isolation. For example, evaluating an e-commerce checkout means testing every step from product search through order confirmation as a connected flow. If any step in the path is inaccessible, the entire scenario fails — making page-level compliance percentages misleading. This approach is particularly valuable for cognitive accessibility because it reveals whether users can maintain context, recover from errors, and follow a logical progression through multi-step processes.
