From our perspective, quality assurance is a subset of the overall usability goal—after all, a website isn’t usable if it isn’t working. Quality assurance is an important step in the website development process and, by all means, must not be skipped. A broken link or a misspelled word may seem like trivial mistakes, but they can greatly undermine the credibility of your website. You want people who visit your site to feel confident about the quality of the information they find.
