Affordance - UI Design
Affordance describes all actions that are made physically possible by the properties of an object or an environment.
Simplicity
Never pursue anything that does not provide direct value to educate or drive sales.
Transparency
Explain every step of the way - if needed. Ensuring no-one is lost when the domain experts leave.
Usability
User Experience must be at the core of all design, creative, and development processes.
