Can Six Sigma Be Useful Outside of Manufacturing?

While Six Sigma was originally developed as a quality control methodology used to improve processes in manufacturing, it can be applied to any process in any industry. Six Sigma can help organizations improve efficiency, reduce costs, and increase customer satisfaction by identifying and eliminating defects in their processes. Some specific ways that Six Sigma can be used outside of manufacturing include:

  • Healthcare. Six Sigma can be used to improve patient safety and reduce medical errors by identifying and addressing the root causes of problems in procedures or patient care.

  • Finance. Six Sigma can be used to improve the accuracy and efficiency of financial reporting, reduce errors in accounting and financial transactions, and improve compliance with regulations.

  • Customer service. Six Sigma can be used to improve the customer experience by identifying and addressing common sources of customer dissatisfaction, such as long wait times or unhelpful service.

In fact, a more detailed look at what Six Sigma does reveals that its activities aren’t manufacturing-specific at all. DMAIC is the acronym that serves as the backbone for any Six Sigma project; it stands for Define, Measure, Analyze, Improve, and Control. Each of the improvements listed above will be accomplished through the following actions:

  1. Define the problem and the goals of the improvement project. This includes identifying the process that needs to be improved, the customer requirements and expectations, and the specific problem or defect that needs to be addressed.

  2. Measure the current performance of the process. This includes collecting data on the process and using statistical tools to analyze it to understand the current state of the process.

  3. Analyze the data to identify the root causes of the problem or defect. This includes using data analysis techniques, such as cause-and-effect diagrams and hypothesis testing, to identify the underlying causes of the problem.

  4. Improve the process by implementing solutions to address the root causes identified in the analysis phase. This may involve making changes to the process, training employees, or implementing new technologies or tools.

  5. Control the process to ensure that the improvements are sustained over time. This includes implementing controls, such as process monitoring and regular audits, to ensure that the process remains stable and continues to meet customer requirements.

DMAIC can be applied to any industry or process. Though the exact steps and tools used in the DMAIC process may vary depending on the specific problem that is being addressed, the overall approach is the same. This approach makes Six Sigma an extremely effective and valuable methodology with versatility to improve processes and eliminate defects for companies in any industry.
