Toyota Lean Clusters Programme Resource Page

Toyota are generally credited as being the source of Lean and Lean thinking in business. When Dan Jones and Jim Womack first tried to understand why Toyota were doing what they were doing and why they were so very good at it – they coined the phrase “Lean”. They identified the Toyota Production System – TPS as the foundation for Toyota’s success.  

Today many of the world’s leading companies have developed their “own” versions of Lean and their own “Production Systems”. There are many similarities and differences between the various Production Systems, but Toyota are at the core of what works, globally. A key element of Toyota success has been the Toyota Production System, but always allied with the Toyota Way…The Big “Why” that drives Toyota team Members to always look to improve.

A fundamental basis within Toyota is that everyone needs to work to understand the Toyota Way and the Toyota production System…everyone has a responsibility to develop their own understanding. These resources will help you to develop YOUR own understanding so that you can apply the basic principles within your own operation. Success is very much dependent on you taking the time and making the effort to absorb, develop and use the basic thinking to make your own business better. These resources will help you do just that, to develop your understanding of tools, techniques and to answer the how and why questions of making them your own, for your business, with your people!
