Lean Six Sigma: How Do Lean and Six Sigma Both Work to Improve Customer Satisfaction?

What Is the Shared Focus of Lean and Six Sigma Methodologies?

Prepare for your Lean Six Sigma certification by learning the shared focus of these two powerful methodologies. While they use different tools, both Lean and Six Sigma are ultimately aimed at reducing process variation and improving customer satisfaction by delivering higher value and quality.​

Question

Which of the following is a shared focus of both Lean and Six Sigma?

A. Increasing headcount in organizations
B. Concentrating only on financial reporting
C. Reducing variation and improving customer satisfaction
D. Eliminating the need for leadership involvement

Answer

C. Reducing variation and improving customer satisfaction

Explanation

Both approaches ultimately aim for higher quality and customer value. Although they have different primary approaches, both Lean and Six Sigma share the ultimate goal of improving business processes to deliver greater value and quality to the customer.​

A Shared Commitment to the Customer

The most fundamental similarity between Lean and Six Sigma is that they are both customer-centric methodologies. Every improvement initiative is ultimately judged by its impact on the customer.​

  • Lean focuses on maximizing customer value by eliminating waste, which it defines as any activity that does not add value from the customer’s perspective.​
  • Six Sigma focuses on meeting customer requirements by reducing defects and variation. It uses the Voice of the Customer (VOC) to define Critical to Quality (CTQ) characteristics that are essential for customer satisfaction.​

Therefore, improving customer satisfaction is the ultimate shared objective that drives both approaches.​

A Common Focus on Process Improvement

Both methodologies achieve their customer-centric goals by focusing intensely on process improvement.​

  • Reducing Variation: This is the primary focus of Six Sigma, which uses statistical analysis to make processes more consistent and predictable. Lean also contributes to reducing variation as a byproduct of its methods, such as standardizing work procedures, which ensures that tasks are performed consistently every time. A process with less variation is more reliable and produces higher-quality outcomes for the customer.​
  • Data-Driven Approach: Both methodologies rely on facts and data to make decisions, moving away from guesswork. Six Sigma is intensely data-driven, using statistical tools throughout the DMAIC process. Lean uses data in a more visual way, through tools like Value Stream Mapping, to identify waste and measure improvements in flow.​

Analysis of Incorrect Options

A. Increasing headcount in organizations: This is incorrect. Both methodologies aim to improve efficiency, which means accomplishing more with the same or fewer resources, not adding to the workforce.​

B. Concentrating only on financial reporting: This is false. While financial benefits are a key outcome, the primary focus is on improving operational processes and customer value. A narrow focus on financials alone is contrary to the holistic approach of Lean Six Sigma.​

D. Eliminating the need for leadership involvement: This is incorrect. Both methodologies require strong and active leadership support to succeed. Roles like the Project Champion are essential for providing resources, removing barriers, and ensuring strategic alignment.​
