The lean startup is a 284 pages book written by entrepreneur Eric Ries. Its goal is to launch a movement of entrepreneurs inspired by the lean manufacturing techniques.
From Ries point of view, one of the biggest modern waste is the waste of time. We are asking people to work on products/projects that doesn’t really matter to the end consumer. We are efficients at doing things that are often useless. After years of experiences in different startups and as a consultant, Ries has adapted the lean manufacturing techniques originally invented by Toyota to the management of a sustainable company.
