Lean Six Sigma: What It Is and How It Helps

Unlock the meaning of lean six sigma: definition, explanation, and benefits

What is Lean Six Sigma?

Lean Six Sigma is a methodology that combines the principles of Lean and Six Sigma to improve performance by systematically removing waste and reducing variation. It is a data-driven approach that focuses on achieving tangible and quantifiable improvements in an organization’s performance.

Origins of Lean Six Sigma

The Lean Six Sigma methodology is a combination of two powerful improvement methods – Lean and Six Sigma. Lean, originating from the Toyota Production System, is a set of tools designed to reduce waste and improve efficiency. Six Sigma, on the other hand, was developed by Motorola and is a data-driven approach aimed at reducing defects and variation in processes.

How Does Lean Six Sigma Work?

The DMAIC Process

The Lean Six Sigma methodology follows a structured process known as DMAIC, which stands for Define, Measure, Analyze, Improve, and Control.

  1. Define: This phase involves defining the problem or the process improvement opportunity.
  2. Measure: In this phase, the current performance of the process is measured.
  3. Analyze: This phase involves analyzing the data collected in the Measure phase to identify the root cause of the problem.
  4. Improve: In this phase, solutions are developed to address the root cause of the problem, and these solutions are then implemented.
  5. Control: This final phase involves monitoring the process to ensure that improvements are sustained over time.

The Role of Lean Six Sigma Belts

In a Lean Six Sigma project, different team members have different roles, which are denoted by different ‘belt’ colors. These include Yellow Belts, Green Belts, Black Belts, and Master Black Belts. Each belt signifies a different level of training and expertise in the Lean Six Sigma methodology.

How Does Lean Six Sigma Help?

Lean Six Sigma helps organizations in several ways. It helps in improving process efficiency, reducing waste, and enhancing product or service quality. By focusing on customer needs and reducing defects and variation, it helps in improving customer satisfaction.

Moreover, Lean Six Sigma also helps in fostering a culture of continuous improvement within the organization. It empowers employees by providing them with the tools and techniques to identify and solve problems, thereby improving their problem-solving skills and increasing their engagement and satisfaction.


In summary, Lean Six Sigma is a powerful methodology that combines the principles of Lean and Six Sigma to drive improvements in process efficiency and product or service quality. By systematically removing waste and reducing variation, it helps organizations in achieving their strategic objectives and enhancing customer satisfaction.
