Six Sigma manufacturing process improvement with SIMUL8


Using simulation to implement Six Sigma principles


The central idea behind Six Sigma is that if you can measure where "defects" (anything that results in customer dissatisfaction) occur in a process, you can systematically figure out how to eliminate them and, through a process of continuous improvement, get as close to "zero defects" as possible.

Six Sigma is divided into two methodologies, DMAIC and DFSS. DMAIC (Define, Measure, Analyze, Improve, Control) focuses on improving existing processes and performance, while Design for Six Sigma (DFSS) focuses on generating new processes, products, and services to meet customer needs (CTQ) at the Six Sigma level.

The statistical rigor available through valid, verifiable simulation and the synergy and capability of simulation software is an ideal fit with either of these methodologies. For example, simulation allows users to compare defects in a Six Sigma analysis process, and even predict six sigma tolerances. For measuring customer satisfaction, simulation is capable of measuring financial, operational and customer satisfaction indicators in the same analysis.
