Book takeaways
- Design is the intersection of human psychology and technology
- “Why?” is the most important question in the world (practice “5 why’s” method as much as possible). Double diamond model <><> is helpful for defining why
- How to design: Observe -> ideate -> prototype -> test -> ITERATE. Iteration is your best friend. “Fail frequently, fail fast”
- There is no such thing as human error. Human error = bad design
- Knowledge is both in the head (declarative knowledge) and in the world (procedural knowledge). Incorporate both in designs
- Constraints are physical, cultural, semantic, and logical. These can hurt you if not thought of, but will help you if used intentionally
