“Principles of design: 1. Use both knowledge in the world and knowledge in the head. 2. Simplify the structure of tasks. 3. Make things visible: bridge gulfs between Execution and Evaluation. 4. Get the mappings right. 5. Exploit the power of constraints. 6. Design for error. 7. When all else fails, standardize.” ―Donald A. Norman, The Design of Everyday Things
