Great article from Superfactory, TPS vs. Lean and the Law of Unintended Consequences [the broken link was removed] by Art Smalley:
Real TPS is not just about “flow” or “pull production” or “cellular manufacturing” or any of the other catchy phrases or tools you may frequently hear. For over fifty years TPS in Toyota has been primarily concerned with making a profit, and satisfying the customer with the highest possible quality at the lowest cost in the shortest lead-time, while developing the talents and skills of its workforce through rigorous improvement routines and problem solving disciplines. In every piece of TPS literature from Toyota, this stated aim is mixed in with the twin production principles of Just in Time (make and deliver the right part, in the right amount, at the right time), and Jidoka (build in quality at the process), as well as the notion of continuous improvement by standardization and elimination of waste in all operations to improve quality, cost, productivity, lead-time, safety, morale and other metrics as needed. This clear objective has not substantially changed since the first internal TPS training manual was drafted over thirty years ago.
This is a great article, I strongly recommend reading it [it is a shame they broke the link]
