Finding and fixing usability problems in an interface leads to a better user experience.
We often think of usability testing as the only method for evaluating the usability of a website or application. There are, however, other methods that can help uncover usability problems.
These methods can be broken down into empirical (usability testing, surveys, and analytics) or inspection methods (expert review, heuristic evaluation, cognitive walkthrough, and guideline review).
Each has their pros and cons but all can be a part of an organization’s approach for uncovering problems and creating a better user experience.
