Product: Principles

10x Rule — To unseat the incumbent, be ten times better — not marginally better.
Build Measure Learn Repeat — The core loop of lean product development.
Bundling and Unbundling of Products — Every product is either being bundled together or torn apart.
Code Is Data — Treat your code, configs, and content as data that can be inspected and transformed.
Customer Experience Success Effort Emotion — A good experience is judged on three things: did it work, how hard was it, and how did it feel?
Doing Everything In-House — Build what's core. Buy the rest. Owning everything isn't a virtue.
Dont Make Me Think — Steve Krug's law of usability: the product should be obvious.
Less but Better — Dieter Rams' design principle: fewer things, done exceptionally.
Less Is More — Constraint breeds clarity. Abundance breeds clutter.
Make It Work Make It Fast Make It Pretty — Three phases, in order: correctness, performance, polish.
Products Lower Cost or Increase Revenue — Every product ultimately sells one of two things to its buyer: save money or make money.
Responding to Change Over Following a Plan — Plans are useful until reality arrives. Then adaptation beats sticking to the plan.
Single Responsibility Principle — One thing, done well. From Unix — do one thing and do it right.
Stop Starting Start Finishing — Limit work in progress. Finish what you start before starting more.
Ways to Dominate Market — Peter Thiel's Zero to One: monopoly comes from one of four moats.
