What Is Six Sigma?
Six Sigma is a globally recognized methodology that helps organizations improve quality, reduce defects, eliminate waste, and enhance process efficiency. Developed by Motorola in the 1980s, it uses a structured, data-driven approach to identify problems, analyse root causes, and implement sustainable improvements. Today, Six Sigma is widely applied across industries such as manufacturing, healthcare, construction, finance, logistics, and information technology to improve performance and customer satisfaction.
Six Sigma follows a belt-based certification system, including White Belt, Yellow Belt, Green Belt, Black Belt, and Master Black Belt. Each level develops progressively advanced skills in process improvement and quality management. Among these, Green Belt Certification equips professionals to lead improvement projects, apply the DMAIC methodology, and deliver measurable business results.
