What is Lean Six Sigma?
Lean Six Sigma is a powerful, data-informed approach to solving problems, improving processes, and reducing wasted time or effort.
Think of it as a structured way to work smarter, helping individuals and organizations eliminate inefficiencies, improve quality, and create better results.
Whether you want to streamline operations, save resources, or improve customer experience, Lean Six Sigma provides the tools to make it happen.
Where Did Lean Six Sigma Come From?
Lean Six Sigma combines two proven methodologies:
Lean, inspired by Toyota’s manufacturing systems focused on efficiency and waste reduction.
Six Sigma, developed by Motorola to improve quality and reduce defects using data.
Since the 1980s, organizations worldwide have used these combined approaches to transform how work gets done.
