Just-In-Time and Lean Systems approaches have been well-established in many companies since the early days of the Toyota Production System. Although more and more service companies are looking for ways to take advantage of Lean Systems thinking, manufacturers are the most common adopters of this approach. The Lean philosophy has also been linked with Six Sigma quality, resulting in many companies implementing "Lean Six Sigma". Has your company, or a company that you are familiar with, adopted the JIT/Lean philosophy? Has it been successful, and if so, what are the main benefits your company has realized? What difficulties were encountered during the transition to lean? If your company has not implemented JIT/Lean, do you think it could benefit from this approach?
