The synergy of the human and technological aspects of Lean form what Henry Ford called a universal code for achieving world-class results in any enterprise. This book expands upon and systemizes this universal code into a structure or framework that promotes organizational self-audits and continuous improvement. The first section offers a foundation of four simple but comprehensive Lean key performance indicators (KPIs): waste of the time of things (as in cycle time), waste of the time of people, waste of energy, and waste of materials. The second section consists of an unofficial (and therefore customizable) standard against which the organization can audit its Lean management system.
