The most successful way of designing for inclusivity is to include users from a broad demographic at every stage of the design process, especially users with physical or cognitive disabilities. This means that extreme users' needs are uncovered early in the research stage and can be then met when prototyping and testing. Working with extreme users' insights throughout the process will ensure the solution is inclusive for users who have not only a permanent disability but also temporary or situational disabilities. Studies have shown that extreme users often don't share their needs in interviews as they feel their frustrations are a result of their disability and not a fault in the system, often these users are more open to sharing their feedback during co-creation workshops when other participants are likely to have had struggles similar to them. We ran a co-creation workshop with extreme users on the last product I worked on and the insights were not only instrumental in increasing the cross-functional team's empathy to ensure we met the users' needs but also helped us create a better solution by reducing the copy and ultimately the cognitive load for all users.
Designing for inclusivity means creating products and services that are accessible to diverse audiences with varying abilities and backgrounds. This involves thorough user research to identify not just primary users, but also marginalized groups and individuals with disabilities. Employing diverse personas helps address a wide range of needs. Additionally, adhering to accessibility standards like WCAG ensures websites and services meet the necessary guidelines for usability.
