Lean Six Sigma
Lean Six Sigma is the combination of two methodologies: Lean and Six Sigma, aimed at improving operational performance, reducing defects, and enhancing overall efficiency in processes. These methodologies originated from different sources but share the common goals of minimizing waste, optimizing processes and delivering high-quality outcomes.
The Lean Six Sigma methodology relies on data and statistical analysis to drive decision-making, ensuring changes are based on evidence rather than assumptions. It places a strong emphasis on understanding and meeting customer requirements by delivering products or services with minimal defects and maximum efficiency.
Lean Six Sigma principles are applicable across many industries, and have been successfully implemented in sectors including manufacturing, healthcare, finance and services. Certifications in Lean Six Sigma are also common, indicating proficiency in the methodologies and tools associated with continuous improvement.
