The concept of accessibility means putting a product or service within reach of as many people as possible regardless of disabilities. Making products accessible is required by some federal laws, such as the Americans with Disabilities Act (ADA) and the Rehabilitation Act. More importantly, however, ensuring products and services are accessible to all is doing the right thing.

User experience is the the overall feeling a person has while using a product such as a website or computer application. In other words, "user experience" means how much customers or visitors enjoy visiting your space. A product that is pleasing and easy to use results in a positive user experience - and positive user experiences result in repeat customers.

Studies show that a high degree of usability yields a better return on investment than almost every other business action. Simply put, if your users can't find your product, they aren't going to buy your product. An effective and efficient website delivers a positive brand image and ensures users come back again.

For most organizations, the most likely answer is "not very well." The usability of a website or application depends on a number of factors, including the needs, wants and limitations of people who are using it, as well as how efficiently they are able to navigate the site. Employing user-centered design ensures a productive, memorable, satisfying customer experience.

The usability of a product is measured by the ease with which users can learn to complete basic tasks. Users of a well-designed product can easily learn the system and remember how to use it, even after a long period of not visiting it. A product with a high degree of usability reduces the number of mistakes users make when completing tasks and makes it easy for them to correct and recover from their mistakes with limited help from other people.

Many accessibility requirements, such as consistent layout, simple error handling and high color contrast are really just principles of good design. All people, regardless of whether they have a disability, prefer environments that are clean and easy to navigate. Incorporating universal design ensures your products are appealing, safe and accessible to all visitors.
