WHY USABILITY?
What are the few reasons how things end up being deemed as unusable?
Poor project planning
Poor User Interface and User Experience
Designers are often well versed with Computer systems and programming languages
Incorrect assumptions with regard to system requirements
Lack of user involvement and training
How many errors do users make when using the application?
Errors
A discipline that software designers can follow to evaluate a business system, website, or mobile application.
Usability
Is it easy to learn?
Learnability
How quick can they perform a certain tasks once they know how to use the application?
Efficiency
Are the commands, controls, and other functions easy to remember?
Memorability
How satisfied are the user with the application?
Satisfaction
It is an element that is displayed when the cursor hover at an icon, hyperlink, image, or other element. It will make it easier to know what that icon is for.
Tooltip
_____ at one computer application but _____ at another one, so users will belong to different categories for particular computer systems.
Novices, experts
These are users who have never used the system before.
Novices
Categories of User
Expert
Occasional
Novices
Novices at one computer application but expert at another one
These are users with detailed knowledge of that particular system.
Expert
These are users who know well how to perform the tasks they need to perform frequently.
Occasional
User response to poor design
Confusion
Boredom
Frustration
Anger
(Example Scenario) Make users guess what to do. Where to look or what to do first. When there are too much details or display in a single page.
Confusion
(Example Scenario) Imagine that deadline of your project is tomorrow and yet you are nowhere near completion because you ended up spending most of your time understanding how to use the required application.
