Lean Enterprise - A business system for organizing and managing product development, operations, suppliers, and customer relations. Business and other organizations use lean principles, practices, and tools to create precise customer value—goods and services with higher quality and fewer defects—with less human effort, less space, less capital, and less time than the traditional system of mass production.

Many of the key principles were pioneered by Henry Ford, who was the first person to integrate an entire production system, under what he termed “flow production." Following World War II, the Toyota Motor Company adapted Ford’s principles as a means of compensating for its challenge of limited human, financial, and material resources. The Toyota Production System (or TPS), which evolved from this need, was one of the first managerial systems using lean principles throughout the enterprise to produce a wide variety of products at lower volumes and many fewer defects than competitors.

Leaders today in a wide range of industries, nonprofit organizations, government agencies, healthcare, and other areas are finding ways to apply the principles of lean as a means of producing goods and delivering services that creates value for the customer with the minimum amount of waste and the maximum degree of quality.

Here are a few more detailed resources:

The Beginner’s Guide to Lean - an article by Dan Jones provides a clear explanation of lean for someone who is just getting started.
Lean Thinking -  The first chapter of this key book by Jim Womack and Dan Jones provides the best 20-page summary of lean thinking available.
Toyota Production System - This article on the Toyota website provides a clear and comprehensive overview of the key principles of lean as defined by the company itself. Note that Toyota chooses to focus on what it defines as the two key pillars of TPS: jidoka, or the highlighting and visualization of problems as a method of building in quality during the manufacturing process; and just-in-time, defined as “making only what is needed, when it is needed, and in the amount needed.
