The Evolution of Quality Management Systems: A Journey of Continuous Improvement
The story of the evolution of quality management systems (QMS) is a testament to the power of continuous improvement. It’s an ongoing quest to enhance the quality of products and services through systematic efforts to detect problems, track progress towards desired outcomes, and adjust for future enhancement opportunities.
From the ancient practices of the medieval guild system to the introduction of modern systems such as Lean and Six Sigma, the evolution of QMS is a fascinating journey. Let’s delve into this historical timeline and reflect on how QMS continues to shape our present and future.
Understanding Quality Management Systems
A QMS is a compilation of processes and practices designed to guide organizations towards continual improvement of their products or services. Encompassing various sectors from manufacturing to healthcare and education, it orchestrates an organization’s activities to meet customer and regulatory requirements and enhance its efficiency and effectiveness. The paramount objective is customer satisfaction.
Tracing the Roots of Quality Management Systems
The genesis of QMS can be attributed to the medieval guild system, where superior craftsmanship signified top-tier product quality. Leapfrogging to the era of the industrial revolution, QMS evolved into factory inspections and the discarding of flawed goods.
In 1911, Frederick Winslow Taylor, a mechanical engineer, pioneered a systematic study of manufacturing efficiency. A few years later, in 1924, Walter Shewhart, a western electric engineer, introduced a statistical quality control method. This laid the foundation for quality management as we know it today, which was most notably adopted by Edward Deming during WWII to accelerate inspections without compromising quality and safety.
However, the true renaissance of modern QMS occurred in post-war Japan. With their economy decimated, the Japanese sought to rebuild their industrial sector, laying the groundwork for the establishment of the Total Quality Management (TQM) methodology.
Total Quality Management and the Quality Revolution
In the wake of the war, Japanese leaders prioritized quality, recruiting American experts like Deming and engineer Joseph Juran, both advocates of statistical sampling. The resultant quality revolution, fostered by methodologies such as the Deming/Shewhart cycle of Plan-Do-Study-Act, instigated a shift from mere inspection to a comprehensive focus on strategies involving processes and people.
In the following decades, Japanese manufacturers progressively refined QMS, which led to the advent of the Toyota Production System—an early form of modern QMS. This resulted in a surge of high-quality, low-cost goods, triggering a global competition centered on quality.
The Rise of Customer-Centric Quality Management Systems
The post-war economic surge amplified customer power, compelling companies to prioritize customer satisfaction over mere product production. In the 1970s, when Japan overtook the U.S. in automobile and electronics manufacturing, it became evident that quality was a key differentiator in the global marketplace. This realization led to the birth of the term “Total Quality Management” and, eventually, the introduction of ISO 9000 in 1987.
The 21st Century Evolution of Quality Management Systems
While TQM played a pivotal role in the early years of quality management in the U.S., recent decades have witnessed the rise of more contemporary strategies like Six Sigma and Lean manufacturing. But what’s next for QMS? Three emerging trends include integration, big data, and risk management. These developments demonstrate how technology and data analysis are transforming QMS, breaking down departmental barriers, enhancing risk awareness, and providing a competitive edge.
Developing and Implementing a Quality Management System
Creating a QMS involves multiple interconnected activities, with an organization’s objectives, needs, and delivered products and services playing crucial roles. The process comprises several phases, including design, build, deploy, control, measure, review, and improve. The eventual goal is to achieve a continuous improvement cycle based on the plan-do-check-act (PDCA) model.
Conclusion
The long and winding road of QMS evolution reflects an unyielding commitment to quality improvement. Regardless of your organization’s approach, it is evident that data and statistical analysis will remain at the heart of a top-tier QMS. As we look towards the future, we can expect QMS to continue playing a pivotal role in driving quality improvement in products and services globally.
