Six Sigma
The Six Sigma Principles focus on reducing variation, improving quality, and enhancing customer satisfaction through data-driven decision-making. Using tools like DMAIC, organisations achieve consistent results by eliminating defects, streamlining processes, and aligning with strategic goals.
Technique Overview
Six Sigma Definition
Six Sigma is a disciplined, data-driven methodology developed to eliminate defects and improve process quality. Originating at Motorola and popularised by GE, it uses the DMAIC framework (Define, Measure, Analyse, Improve, Control) to identify root causes of variation, reduce waste, and achieve measurable performance gains. Six Sigma aligns operations with customer needs through rigorous analysis and continuous improvement.
