Success Criteria
Efficient Paths (Machine Testable)
The path taken to access the service (the initial contact with the website or service) should be as efficient and as simple as possible (time required to complete an action displayed, reducing too much choice, ensuring visitors know what's required at the start of a complex set of steps, etc).
Patterns For Efficiency (Human Testable)
The users journey (when browsing an accessed website or service) should be as smooth as possible. User-research is key, as is building on established design patterns that people already understand.
Distraction-Free Design (Machine Testable)
Visitors can complete tasks without distractions or non-essential features getting in the way.
Eliminate The Non-Essential (Machine Testable)
Visitors see only information that is relevant to their experience, without non-essential information being displayed on the screen.
User-Initiated Actionable Content (Machine Testable)
Ensure that actionable information such as pop-up or modal windows can only be initiated by the visitor.
