This article explores the answer to the question “What is Lean Six Sigma?”, detailing its core principles and the significant benefits it offers to organizations aiming for operational excellence. It explains how Lean Six Sigma combines the waste reduction focus of Lean with the quality improvement tools of Six Sigma to drive efficiency and effectiveness. KPI Fire’s Lean Six Sigma Software is highlighted as an essential solution that integrates these methodologies, providing your organization with powerful tools to manage continuous improvement programs and achieve strategic goals.
Introduction: What is Lean Six Sigma?
Lean Six Sigma is a data-driven methodology that combines the efficiency of Lean principles with the quality focus of Six Sigma. Lean and Six Sigma are respectively and historically defined as two separate methodologies that can be categorized under the umbrella term of Business Improvement. More recently, these two methodologies have been merged into a common philosophy and referred to as one: Lean Six Sigma.
By eliminating waste, reducing defects, and optimizing processes, organizations can significantly enhance performance, customer satisfaction, and bottom-line results. The adoption and application of Lean Six Sigma principles empower businesses to achieve sustainable growth and gain a competitive edge.

The best choice depends on your specific goals, business processes, team skills, and organizational culture.
Historical Background: Origins of Lean and Six Sigma
The history of Lean and Six Sigma can be traced back to the early 20th century, with significant contributions from both the United States and Japan. Henry Ford’s introduction of the assembly line in 1913 revolutionized manufacturing, and while Ford laid the groundwork, Toyota took these concepts further. Enter the Toyota Production System (TPS), which is the foundation of Lean as we know it today. The term “lean” was only officially coined in the 1980s by researchers at the Massachusetts Institute of Technology, who deemed Toyota’s approach to be far more significant than others.
As a close concept to Lean, although developed on its own, Six Sigma was pioneered by Bill Smith at Motorola in the 1980s. The company was facing increasing competition and quality issues, leading Smith to develop a rigorous methodology to improve product quality and overall business performance. The name “Six Sigma” is derived from statistical process control, representing a process that produces only 3.4 defects per million opportunities. This level of quality was the ambitious goal set by Motorola.
Core Principles of Lean Six Sigma
At its core, Lean Six Sigma emphasizes eliminating the 8 wastes and improving efficiency. Below, we review core Lean Six Sigma principles or foundations that make up a “House of Lean” and what they entail for organizations across multiple industries.
- Waste elimination: Visualizing the entire process with Value Stream Mapping to identify waste and inefficiencies.
- Continuous Improvement: Fostering a culture of ongoing process enhancement and improving efficiency.
- Holistic & Employee Driven: Engaging employees in the improvement process.
- Customer Focus: Understanding and meeting customer needs and expectations.
- Defects Reduction: Minimizing errors and defects in products or services.
By adhering to these principles, organizations can significantly enhance their operations, reduce costs, and improve customer satisfaction. Lean emphasizes eliminating waste and improving efficiency.
What is Six Sigma? Understanding its Focus
Six Sigma is a data-driven methodology that aims to improve the quality of business processes by identifying and eliminating defects and minimizing variations. It’s a structured approach to problem-solving that uses statistical methods and a set of tools to achieve significant process improvement.
- Reducing Defects: The primary goal is to minimize errors and defects in products or services.
- Process Improvement: Enhancing the efficiency and effectiveness of business processes.
- Data-Driven Decision Making: Relying on statistical analysis and data to guide problem-solving.
- Customer Satisfaction: Ultimately, improving customer satisfaction by delivering higher quality products or services.
By employing a systematic approach and focusing on measurable results, Six Sigma has been successfully implemented in various industries to enhance productivity, reduce costs, and increase customer loyalty.
Lean vs. Six Sigma: Understanding the Differences
Lean Six Sigma is a powerful combination of two methodologies that complement each other to drive significant process improvement. While Six Sigma focuses on reducing variation and defects, Lean emphasizes eliminating waste and improving efficiency. Consider the video below to fully grasp the differences between these closely related terms. We would also recommend brushing up on essential lean concepts and terms to supercharge your greater understanding.
Key Steps for Integrating Lean into Six Sigma
By integrating Lean principles into the Six Sigma framework, organizations can achieve accelerated results and a more holistic approach to process optimization.
1. Align Strategic Goals:
- Clearly define the organization’s strategic objectives.
- Ensure Lean Six Sigma initiatives align with these goals.
2. Build a Strong Foundation:
- Leadership Commitment: Secure top-level support for the initiative.
- Culture Change: Foster a culture of continuous improvement and employee involvement.
- Training: Provide comprehensive training in both Lean and Six Sigma methodologies.
3. Identify Improvement Opportunities:
- Conduct a thorough process assessment using Lean tools like value stream mapping.
- Prioritize opportunities based on their potential impact and feasibility.
4. Combine Lean and Six Sigma Tools:
- Use Lean tools such as value stream mapping and 5S to identify waste and process inefficiencies.
- Apply Six Sigma tools such as DMAIC and statistical analysis to eliminate defects and reduce variation.
- Consider a hybrid approach, combining tools from both methodologies as needed.
5. Pilot Projects:
- Implement Lean 6 Sigma projects on a smaller scale to test the approach.
- Analyze results and make adjustments as needed.
6. Expand and Sustain:
- Replicate successful projects across the organization.
- Establish a Lean Six Sigma infrastructure for ongoing improvement.
- Embed Lean Six Sigma principles into the company culture.
Key Integration Points:
- Value Stream Mapping: Use it to identify waste and then apply Six Sigma tools to eliminate root causes.
- DMAIC: Incorporate Lean principles into the Define and Measure phases to focus on customer value and process flow.
- Kaizen: Use Lean’s continuous improvement philosophy to sustain Six Sigma gains.
Kaizen in Lean Six Sigma
Kaizen, meaning “continuous improvement” in Japanese, is a fundamental principle underpinning Lean Six Sigma. Kaizen in Lean Six Sigma could be described as the philosophy of making small, incremental changes to processes and systems over time. Kaizen in Lean Six Sigma serves as the cultural backbone, fostering a mindset of constant improvement among employees at all levels. It complements the structured DMAIC methodology by providing a more organic approach to problem-solving.
Key Tools and Techniques in LSS
A variety of tools and techniques are used within the Lean Six Sigma framework to eliminate waste and reduce defects. Here’s a breakdown of some of the most commonly used ones in each phase of DMAIC.
Define Phase
- Customer Segmentation: Identifying different customer groups and their specific needs.
- Voice of the Customer (VOC): Understanding customer expectations and requirements.
- Project Charter: Outlining project goals, scope, and deliverables.
