The scientific method is a standardized way of making observations, gathering data, forming theories, testing predictions, and interpreting results. Researchers make observations in order to describe and measure behavior.

This is the article to give to your boss or anyone else who doesn't have much time, but needs to know the basic usability facts. What — Definition of Usability Usability is a quality attribute that assesses how easy user interfaces are to use.
The word "usability" also refers to methods for improving ease-of-use during the design process. Usability is defined by 5 quality components: How easy is it for users to accomplish basic tasks the first time they encounter the design?
Once users have learned the design, how quickly can they perform tasks? When users return to the design after a period of not using it, how easily can they reestablish proficiency? How many errors do users make, how severe are these errors, and how easily can they recover from the errors?
How pleasant is it to use the design? There are many other important quality attributes. A key one is utility, which refers to the design's functionality: Does it do what users need?
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.
If a website is difficult to use, 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.
For intranets, usability is a matter of employee productivity. Time users waste being lost on your intranet or pondering difficult instructions is money you waste by paying them to be at work without getting work done. For software and physical products, the improvements are typically smaller — but still substantial — when you emphasize usability in the design process.
For internal design projects, think of doubling usability as cutting training budgets in half and doubling the number of transactions employees perform per hour. For external designs, think of doubling sales, doubling the number of registered users or customer leads, or doubling whatever other KPI key performance indicator motivated your design project.
How to Improve Usability There are many methods for studying usability, but the most basic and useful is user testing, which has 3 components: Get hold of some representative userssuch as customers for an ecommerce site or employees for an intranet in the latter case, they should work outside your department.
Ask the users to perform representative tasks with the design. Observe what the users do, where they succeed, and where they have difficulties with the user interface.
Shut up and let the users do the talking.
It's important to test users individually and let them solve any problems on their own. If you help them or direct their attention to any particular part of the screen, you have contaminated the test results.
To identify a design's most important usability problems, testing 5 users is typically enough.Artificial intelligence (AI), sometimes called machine intelligence, is intelligence demonstrated by machines, in contrast to the natural intelligence displayed by humans and other animals.
