Did you know that quality control, which once relied on artisanal methods, has evolved into sophisticated, technology-driven processes? The journey of quality control began in the ancient world, where craftsmanship was the cornerstone of quality. Artisans, revered for their skills, took immense pride in their work. Each product was meticulously crafted, and the artisan's reputation hinged on the quality of their output. This personalized approach ensured high-quality outputs but needed to be more scalable. Today, products such as pottery, textiles, and metalwork are inspected using cutting-edge technologies like AI and IoT, a far cry from the individual inspections of the past.
It was the 18th century, towards the end of it, to be precise, when the prospects of quality control gathered some momentum. Thus, the increase in industrial production saw the need for more structured approaches to QC. Inspection and sorting started to be posted in factories to prevent unreliable products. The first systematic approaches of QC and the means of standardized production can be attributed to this period. However, these early methods were still rudimentary; the inspection process was often done manually and was time-consuming.
The first significant leap in QC’s evolution occurred in the 1920s, with the introduction of an approach called ‘statistical quality control’ by Walter A. Shewhart. This was a significant change that focused on the application of statistical tools to measure and regulate quality within production. It shifted from merely inspecting items at the end of the line, where the problem could only be found and not solved, to a proactive approach that prevented defects instead of just detecting them. This was a pivotal moment in the history of QC, enlightening us about the power of statistical tools in maintaining quality.
The third major landmark in the evolution of quality control was attained in the post-World War II period when W. Edwards Deming played a pivotal role in propagating quality management principles to Japanese manufacturers. Out of Deming’s approaches that focused on daily improvement and the proper effects, radical product quality and reliability improvement were achieved. His teachings also set the stage for what is now called Total Quality Management (TQM), but more importantly for the Japanese manufacturing society, where quality became an essential trademark of made-in-Japan products.
