My personal notes from The Lean Startup by Eric Ries

• Identify where you’ve made assumptions instead of using facts. Make your assumptions facts by getting customer feedback
• Early adopters are suspicious of something with too much polish.
  • If it’s ready for everyone to adopt how much advantage can they get?
  • Additional features or polish added is a waste
• When in doubt simplify.
• Any additional work beyond what was required to get feedback is a waste
• Customers don’t care how much time something takes to build they care that it solves their needs
• Everyone thinks their recent innovation is why the numbers went up. It’s everyone else’s fault when numbers go down.
• Toyota Andon Cord
  • Defective change is removed immediately and automatically
  • Everyone on the relevant team is notified of the problem
  • Team is blocked from introducing any new changes
  • Root cause analysis performed
• Dealerships sometimes have just in case inventory which cost a lot of money to keep stock on hand that we never be needed switch to just-in-time inventory and only have a one what you need
• Use 5 why’s? to answer questions
  • “We didn’t do x”, “Why didn’t you do x?”
  • “We didn’t do x because of y”, “Why didn’t you do y?”
• LTSE long term stock exchange
