Countless pieces of research have shown that usability is important in product choice, but perhaps not as much as users themselves believe; it may be the case that people have come to expect usability in their products.

This growing expectation puts even more pressure on designers to find the sweet spot between function and form. It is meanwhile critical that product and web developers retain their focus on the user; getting too lost within the depths of their creation could lead to the users and their usability needs getting waylaid.

Through the knowledge of how best to position yourself as the user, you can dodge this hazard. Thanks to that wisdom, your product will end up with such good usability that the latter goes unnoticed! A usable website, for example, is often overlooked when considering the expansion of a business.

Usability is key to growth, user retention, and satisfaction. So, we must fully incorporate it into anything we design. There are other myths in many organizations about usability that should be identified, understood and mitigated, such as being expensive, esthetically pleasing or asking what a persons preferences are. Usability is expensive This is never the case. Usability testing can be as simple as a free questionnaire or having a friend or colleague use your product.

The more types of testing and more actual end-users you test the more accurately you will shape the usability of your product. You get out of testing exactly what you put in.

Usability and utility are equally important and together determine whether something is useful: It matters little that something is easy if it's not what you want. It's also no good if the system can hypothetically do what you want, but you can't make it happen because the user interface is too difficult.

To study a design's utility, you can use the same user research methods that improve usability. On the Web, usability is a necessary condition for survival. If a website is difficult to use, people leave. If the homepage fails to clearly state what a company offers and what users can do on the site, people leave.

If users get lost on a website, they leave. If a website's information is hard to read or doesn't answer users' key questions, they leave. Note a pattern here? There's no such thing as a user reading a website manual or otherwise spending much time trying to figure out an interface.

There are plenty of other websites available; leaving is the first line of defense when users encounter a difficulty. The first law of ecommerce is that if users cannot find the product, they cannot buy it either.
