Organizations often seek opportunities to improve their competitive advantage within their respective industries. Many organizations struggle to accomplish this goal without the use of a systematic approach to improve their organizational performance as it relates to quality products or services. Lean and Six Sigma are proven quality techniques that can help improve organizational performance. Although most organizations want to improve quality and cut costs, the deployment and implementation of continuous improvement methodologies is commonly viewed as a daunting undertaking.

For various reasons, some organizations focus their efforts on implementing Lean concepts, while others focus their efforts towards the implementation of Six Sigma methodologies. Lean is considered to be a systematic approach of eliminating waste in all processes of an organization and is based on the Toyota Production System (TPS). The term Six Sigma was coined by engineers at Motorola in the 1980’s which focuses primarily on reducing variation within a manufacturing or business process. Six Sigma improvements are based on a structured problem-solving methodology which requires project management skills.

Many organizations seem to find the appropriate balance of integrating both Lean and Six Sigma within their organizations to achieve optimal improvement performance. The term Lean Six Sigma represents this collaborative approach. By incorporating the tools and concepts of Lean into the structured DMAIC (Define, Measure, Analyze, Improve and Control) framework of Six Sigma, organizations are reaping the benefits of two very powerful and effective quality improvement methodologies.
