The Lean Startup, by Eric Ries

By now many start ups have successfully implemented the formula of rapid experimentation, continuous testing, incorporating feedback and pivoting.

Eric Ries’ lean start up method remains a classic in entrepreneurship. Ries’ scientific approach to measuring actual progress and learning what customers really need has changed how products are launched and how companies are built – allowing for increased agility in adapting and building a business towards sustainable success.

Though a lot of the examples are tech related, the lean start up philosophy is relevant to any type of business, at any stage of development.
