What are the five 5 goals of usability?
An understanding of the five characteristics of usability – effective, efficient, engaging, error tolerant, easy to learn – helps guide the user-centered design tasks to the goal of usable products.
How can an effective problem statement help a UX designer establish goals?
An effective problem statement tells you what the user really needs. By defining the goal clearly and concisely, it gets all members of the design team involved and focused on the same thing. Problem statements help us understand constraints. We want to know what's keeping users from getting their needs met.
Which usability principles are especially important in the design of help systems?
The first and therefore most important rule is the observance of effectivity. An application should enable the user to work effectively by providing a suitable functionality for the completion of his task. The user is not overloaded with information and functions that are not necessary for his use case.
