Plasma Cutter Cycle Time Experimental Design Results

This post describes the results and their analysis of the experimental design to reduce plasma cutter cycle time.  The experimental design is a Taguchi Parameter Design.   The previous posting describes the experimental design, and refers to the Value Stream Map Case Study posting to review the Lean Six Sigma project that produced the experimental design.   Continue reading Plasma Cutter Cycle Time Experimental Design Results

Experimental Design to Reduce Plasma Cutter Cycle Time

This posting describes the corrective action using an experimental design to reduce a machine’s cycle time.  The machine is a plasma cutting machine, and a Lean Six Sigma (LSS) team identified it as the bottleneck operation in producing electrical switchboards by an electrical manufacturer.    Continue reading Experimental Design to Reduce Plasma Cutter Cycle Time

Testing the Effectiveness of the Integrated Methodology including the Theory of Constraints, Lean and Six Sigma, Part 2

The previous posting gives an overview of the experiment comparing project outcomes using Lean, Six Sigma and TLS.  Continue reading Testing the Effectiveness of the Integrated Methodology including the Theory of Constraints, Lean and Six Sigma, Part 2

Testing the Effectiveness of the Integrated Methodology including the Theory of Constraints, Lean and Six Sigma, Part 1

The previous posting describes the system improvement methodology, called TLS integrating the Theory of Constraints (TOC), Lean and Six Sigma, Continue reading Testing the Effectiveness of the Integrated Methodology including the Theory of Constraints, Lean and Six Sigma, Part 1

Effectiveness of Integrated Theory of Constraints and Lean Six Sigma Methodology

Pirasteh and Farah (2006) describe the results of an experiment to compare the results of process improvement projects using Lean, Six Sigma, an integrated approach using the Theory of Constraints (TOC), Lean and Six Sigma. Continue reading Effectiveness of Integrated Theory of Constraints and Lean Six Sigma Methodology

Integrated Six Sigma and the Theory of Constraints – Axle Factory Case Study

Ehie and Sheu (2005) describe an application of their integrated framework for Six Sigma (SS) and the Theory of Constraints (TOC) by a company supplying vehicular components to automotive manufacturers.  Continue reading Integrated Six Sigma and the Theory of Constraints – Axle Factory Case Study
