This document discusses how lean startup principles can be applied within large enterprises. It notes that lean startup has been around since the 1970s and was popularized by Eric Ries' book The Lean Startup. The document advocates for empowering "intrapreneurs" within companies, fixing learning loops, explaining the reasons for changes to different departments, and decoupling new projects from the main company brand to allow for more experimentation and risk-taking. It asserts that these practices can help large companies learn faster and better adapt to extreme uncertainty.
