A typical user will want all of these elements when performing a task.
It is very important that we design with the user in mind...
Accomplishing a goal should be obvious to the user, without confusion or explanation.
2. Responsiveness & Feedback
Micro-tasks should be validated with feedback. Failure to provide appropriate feedback pulls focus away from the goal and forces an intense focus on micro-tasks.
Performance issues indicate a poorly engineered product or technical malfunction.
4. Intuitiveness & Efficiency
The degree to which the process of accomplishing a goal is obvious.
A solution may solve a business problem without considering user needs but in the end will have a negative effect on the business.
6. Relevant, Valuable Content
Well timed, relevant content can increase user satisfaction and drive sales. (e.g. "Things you might also consider" when buying a product is a good example of this).
7. Internal Consistency
The website, application or interface should handle similar tasks in similar ways. Consistent visual design gives the impression of a unified, well-organised, professional product.
8. External Consistency
The visual appearance of a product should indicate its purpose and audience. This is also the case with branding standards.
9. Appropriateness To Context
The use of language or imagery should be appropriate to the context.
Issues that break engagement also injure the trustworthiness of a product.
