  What is Usability?

"Usability addresses the relationship between tools and their users. In order for
a tool to be effective, it must allow intended users to accomplish their tasks
in the best way possible. The same principle applies to computers, websites, and
other software. In order for these systems to work, their users must be able to
employ them effectively" (Foraker Design , 2005).

• Why is Usability Important?

From the user's perspective usability - it can make the difference between a good or bad user experience with product

From the developer's perspective - it can mean the difference between the success or failure of a design.

Developers that do not think about usability would have wasted their time and effort on the system/design as usability greatly determines the success or failure of a system and people will tend to go for the those that are more user-friendly (Foraker Design , 2005).
