The Lean Startup – Eric Ries
My notes from the book The Lean Startup by Eric Ries:
Split testing often uncovers surprising things. Many features that make the product better in the eyes of engineers and designers have no impact on customer behavior.
Are we making sufficient progress to believe that our original specific strategic hypothesis is correct or do we need to make a mayor change. That change is called a PIVOT - a structured course correction designed to test a new fundamental hypothesis about the product, strategy and the engine of growth.
Single piece flow - one envelope at a time. It works because of a surprising power of small batches.
It matters how fast you can get through the entire loop of build measure learn.
