TLS

TLS (TOC[1], Lean [2], Six Sigma [3]) as an alternative continuous improvement approach was introduced by Reza M. Pirasteh, Ph.D. [4]in 2003. TLS utilizes TOC (Theory Of Constraints), Lean and Six Sigma principals in a special sequence which delivers higher results as if each one of the continuous methodologies were used individually. To determine the effectiveness of the three methodologies, an experiment was designed that collected data for over 2 years. The results were statistically analyzed for significance between the three methodologies. Lean and Six Sigma were identified as viable continuous improvement methodologies. The success of each methodology was determined by their aggregate contribution to verifiable financial savings as a result of process improvement projects. These savings were validated with the organization plant controllers and senior management. Results of research were published in APICS [5] (American Production Inventory Control Society) magazine “Continuous Improvement Trio”[6] (Pirasteh, R., Farah, K.[7]). TLS process improvement methodology appeared significantly more effective compared with the other two methodologies, Lean and Six Sigma, by delivering higher cost savings. In this study TLS methodology application resulted in a contribution of 89% of the total savings reported, followed by 7% from Six Sigma and 4% from Lean applications. During this study, 101 projects were completed by the three methodologies. Data indicated that TLS projects delivered on average 2.591 times higher savings that Lean and 3.866 times higher than Six Sigma.
