In a world where even a tiny mistake can cost a company millions, Six Sigma is like a safety net. It helps businesses identify flaws and fix them before they turn into bigger problems. Whether you’re running a startup or working in a multinational company, Six Sigma gives you the tools to deliver quality consistently.
What is Six Sigma?
Six Sigma is a data-driven methodology that focuses on reducing defects and improving processes. The goal is simple: achieve near perfection — only 3.4 errors per million chances.
Example: Imagine a mobile phone company producing 1 million devices. If they follow Six Sigma standards, only about 3–4 phones would have defects. That’s the level of quality we’re talking about.
History & Evolution of Six Sigma
Six Sigma began in the 1980s at Motorola. They were facing quality issues in their electronics, so they developed this strategy to improve manufacturing. Soon, companies like General Electric adopted it and saved billions.
Since then, it has evolved into a universal quality tool — not just for manufacturing but also for healthcare, finance, IT, education, and more.
Example: Hospitals use Six Sigma to reduce the time patients wait in emergency rooms, improving both care and efficiency.
