Usability is the ease of use and learnability of a human-made object. The object of use can be a software application, website, book, tool, machine, process, or anything a human interacts with.
We adhere to the design principles of usability in everything we do. Websites and apps don’t come with a user manual and we have a limited time to direct the user to the information they require. If users get frustrated with looking for content, they leave. If users can’t do whatever task they need to on your website, they leave.
We design everything we do to ensure ease of use and provide users with “stress free” online experiences.
Consistency is one of the most powerful usability principles: when things always behave the same, users don’t have to worry about what will happen. Instead, they know what will happen based on earlier experience.
