This lean thinking webcast from India actually does a pretty decent job of providing an overview (for a business TV channel) even if they get some things a bit confused. The discuss TQM in India preceding lean which is an accurate view in my opinion – quality management shared many lean principles. They even talk of lean at Ford doing lean first. But they get the decades for that a bit off. They seem to mash together the “quality is job one” refocus on quality lead by Dr. Deming in the 1980’s with Henry Ford in the early 1900’s.
The webcast includes Jim Womack discussing lean thinking. He mentions the misunderstanding of lean as primarily cost cutting.
