Six Sigma strategy focuses on achieving measurable and quantifiable financial returns to the bottom-line of an organisation.

Six Sigma methodology of problem solving integrates the human elements (culture change, customer focus, belt system infrastructure, etc.) and process elements (process management, statistical analysis of process data, measurement system analysis, etc.) of improvement.

Six Sigma methodology utilises the tools and techniques for fixing problems in business processes in a sequential and disciplined fashion. Each tool and technique within the Six Sigma methodology has a role to play in the process improvement or trouble shooting, and the time, location, reason and method of application of these tools or techniques marks the difference between success and failure of a six sigma project.

Six Sigma emphasizes on the importance of data, and decision-making is undertaken based on facts and data rather than assumptions.

Six Sigma utilises the concept of statistical thinking and emphasises on the application of well-proven statistical tools and techniques for defect reduction through process variability reduction methods (e.g., statistical process control and design of experiments).

Implementation of Six Sigma

Over the past few years, Six Sigma has evolved from a mere strategy for improving quality to a strategy that has become a necessity for achieving business goals.
