This technique is popularly known as the Lean Startup movement, which was created by Eric Ries and Steve Blank and is based on Ries’s book of the same name. The Lean Startup philosophy (also known as the Lean Launchpad) is in turn based upon Toyota’s “lean manufacturing” principles, first established a half-century ago, in which the elimination of wasteful processes is paramount. (Sample principle: “Eliminate all expenses with any goal other than the creation of value for the end customer.”)
