Lean means a lot of things to a lot of people. To some, “running lean” means cost cutting to the bare minimum. To others, Lean Manufacturing is all about reducing waste without sacrificing quality or productivity. In the world of entrepreneurship, the Lean Startup methodology offers an approach to building business through practices of experimentation, iterative development, and validated learning.
To me, the most important principle of lean is this:
Focus the precious time and resources you have on the right things, and don’t waste or invest new resources on the wrong things.
