Why Should Process Improvement Ultimately Satisfy Customers?
Prepare for your Six Sigma Green Belt exam by understanding why customer focus is central to the methodology. Learn how the ultimate goal of any process improvement is to increase value and satisfaction for the customer, which drives all Six Sigma initiatives.
Question
Why is customer focus central to Six Sigma?
A. Because customers design statistical models
B. Because customers manage project roles
C. Because it simplifies accounting processes
D. Because improving processes should ultimately satisfy customers
Answer
D. Because improving processes should ultimately satisfy customers
Explanation
Customer value drives Six Sigma improvements. The fundamental principle of Six Sigma is that all improvement efforts are ultimately worthless unless they deliver greater value to the customer.
The Customer as the Ultimate Judge of Quality
In the Six Sigma philosophy, the customer is the final arbiter of quality. An organization can have the most efficient, streamlined, and low-cost process in the world, but if the end product or service does not meet the customer’s needs and expectations, the process is a failure. For this reason, customer focus is not just one component of Six Sigma; it is the starting point and the guiding star for the entire methodology.
This customer-centric approach is embedded in the DMAIC (Define, Measure, Analyze, Improve, Control) framework:
- The Voice of the Customer (VOC): The Define phase begins with a concerted effort to capture the Voice of the Customer. This involves gathering direct feedback through surveys, interviews, and market analysis to understand what customers truly want and expect.
- Critical to Quality (CTQ): The VOC is then translated into specific, measurable, and actionable internal metrics known as Critical to Quality (CTQ) characteristics. These CTQs become the basis for the project’s goals. For example, a customer’s vague desire for “fast service” might be translated into a CTQ of “time from order to delivery is less than 24 hours.”
- Defect Definition: A “defect” in Six Sigma is formally defined as any output that fails to meet a CTQ characteristic. This means that the entire effort to reduce defects is directly tied to improving what matters most to the customer [ax].
By structurally aligning process improvement goals with customer requirements, Six Sigma ensures that it is always working to enhance customer satisfaction, which in turn drives loyalty, market share, and profitability.
Analysis of Incorrect Options
A. Because customers design statistical models: This is false. The design and application of statistical models are highly technical tasks performed by trained Six Sigma practitioners, such as Green Belts and Black Belts.
B. Because customers manage project roles: This is incorrect. Project roles like Champion, Black Belt, and Green Belt are internal management structures within an organization. Customers are external stakeholders whose needs inform the project; they do not manage it.
C. Because it simplifies accounting processes: This is not the primary reason. While the cost savings from Six Sigma projects will certainly be reflected in financial accounts, the methodology’s core focus is on improving operational processes to satisfy customers, not on redesigning accounting procedures.
