The Power of ISO 9001:2015 and Six Sigma in Business

The combined power of ISO 9001:2015 Certification and Six Sigma methodologies are game-changers for business looking to gain a competitive edge. With unparalleled efficiency and quality control measures, these two approaches can streamline your operations and maximize your profits.

The Overview of ISO 9001:2015 Certification:

What is ISO 9001:2015 Certification?

ISO 9001:2015 is an internationally recognised quality management standard that provides a framework for organisations to ensure that their products and services consistently meet client’s requirements and expectations.

Why is it Important?

ISO 9001:2015 certification is important because it demonstrates to customers that you are committed to providing high-quality products and services. It also helps to improve the effectiveness and efficiency of your operations.

How to Get Certified?

Getting certified involves a series of steps, including conducting an internal audit, preparing documentation, undergoing an external audit by a certified body, and maintaining certification through ongoing surveillance audits.

Overview of Six Sigma:

Six Sigma is a data-driven and customer-focused methodology that uses statistical analysis to identify and eliminate defects, errors, and waste in business processes. It is designed to help organisations improve quality, reduce costs, and increase customer satisfaction.

The Benefits of Six Sigma:

1. Improved Efficiency:

Six Sigma helps to identify and eliminate inefficiencies in processes, reducing waste and increasing productivity.

2. Better Products/Services:

The focus on improving quality leads to better products and services, increasing client satisfaction and loyalty.

3. Increased Profit Margin:

By reducing waste and improving efficiency, Six Sigma can help organisations to increase their profit margins.

4. Continuous Improvement:

Six Sigma encourages a culture of ongoing improvement, ensuring that organisations continue to remain competitive and relevant in their markets.

The Integration of ISO 9001:2015 and Six Sigma:

The integration of these two approaches can help to create a comprehensive and effective quality management system. By combining the process-oriented approach of Six Sigma with the customer-oriented approach of ISO 9001, organisations can achieve unprecedented levels of efficiency and customer satisfaction. This integration requires a thorough understanding of both methodologies and their interdependence to create a seamless system. Here’s how they can work together:

Alignment: ISO 9001:2015 focus on client satisfaction and process improvement aligns well with Six Sigma’s goals, Organisations can use Six Sigma to implement the principles and practices required by ISO 9001.

Data-Driven Improvement: Six Sigma’s data-driven approach can be integrated into ISO 9001 emphasis on monitoring and measuring processes. This ensures that any improvements are based on accurate data.

Structured Problem Solving: Six Sigma’s DMAIC (Define, Measures, Analyse, Improve, Control) methodology can be used to address non-conformities identified through ISO 9001 audits.

Continuous Improvement: Both ISO 9001:2015 and Six Sigma promote a culture of continuous improvement. By combining them, organisations can create a robust system for ongoing enhancement of their processes and quality management.

ISO 9001:2015 Certification Requirements:

Scope: This specifies the boundaries and applicability of your quality management system.

Leadership: Top management must be actively involved in driving and implementing the quality management system.

Planning: The organisation must have a systematic approach to planning and setting quality objectives.

Support: Your workforce must have the necessary resources to perform their duties and continuously improve.

Operation: The organisation must have efficient processes and controls in place to ensure that products and services conform to requirements.

Performance Evaluation: You must monitor and analyse your QMS’s performance through metrics and reports.

Improvement: You must continuously improve your processes and overall QMS performance.


In conclusion, ISO 9001:2015 certification and Six Sigma are powerful tools on their own, but when integrated effectively, they can help organisations achieve higher levels of quality, efficiency, and client satisfaction while maintaining a strong focus on continuous improvement. This integration can give business a competitive edge in today’s dynamic and client-centric markets.
