Usability is the general user friendliness of a product, in this case - of a web application. The objective is to achieve a simple, intuitive and quick operation of a website for all users. A good usability usually goes unnoticed with the users, a bad one – even more so.
What counts in Usability
The usability indicates how friendly a product is for its user, in short: user friendliness. Also the fitness for purpose and the intuitive user guidance are terms which describe well the usability of software programmes, websites, user interfaces and design.
Already over 20 years ago, usability expert Jacob Nielsen determined 5 principles defining the quality of usability:
- Learnability: How easy it is for users to complete basic tasks when they are dealing with the product for the first time?
- Efficiency: How quickly can users finish their tasks once they got to know the design (product)?
- Memorability: How easy is it for the users to find their way when they want to go back to the design (product) after a while?
- Errors: How many mistakes do the users make? How serious are those mistakes? How easily can they get over those mistakes?
- Satisfaction: How enjoyable is it to utilise the design (product)?
A poor usability of a website has numerous negative consequences:
- The website is not speaking for itself. It is not clear for the user what the company is offering and what he can do on the website.
- The user cannot find the essential products or information.
- The user is frustrated, is quitting the website and is switching over to the competition.
On the other hand, if a user comes across a website with high usability, he or she stays on the site with a good feeling of satisfaction - with many positive effects:
- The user remains longer on the website.
- The user can find the products and services he is looking for.
- The user becomes a customer.
The user recommends the site further to his friends and acquaintances.
