This is a damn good definition of Lean: “satisfying customers by developing people”. Great improvement from old-time definitions about “improving processes”, “eliminating waste” or the horrifying “cutting costs by firing people” (well, this has never been a serious definition, but sadly many people interpreted lean methods like that).
Please, don’t take me wrong: improving your processes and eliminating waste (mercilessly) are great things to do, but they are means, not a goal. Cutting costs is fantastic too, but it must be more the result of your efforts to create value and satisfy your customers than a goal by itself. And firing people, well… Developing people so that they can satisfy your customers is the only recipe to long-term success, which is the ultimate goal of any company.
