Usability is a term used to denote the ease with which people can employ a particular tool or other human-made object in order to achieve a particular goal.
Usability is not a new philosophy or process. It’s been around for years. So why so many web failures? Usability alone can’t answer the business or tech questions. It can measure the end user.
Some these days misuse the term Usability. Simply put, we can understand your user to better communicate your business value and in the end that is usability according to us.
