What is Quality Control?
Quality control is the process of ensuring that a product or service meets the defined standards and requirements. Fundamentally, quality control guarantees that the product or service satisfies customer expectations and is free from defects, deficiencies, or deviations. This process aims to secure quality through various inspections, tests, and examinations conducted during and after production.
Quality control aims to improve the product and the production processes, enhance customer satisfaction, and reduce costs. This approach is supported by statistical methods, process controls, and continuous improvement (Kaizen) in modern manufacturing systems, aiming to increase efficiency and minimize errors. After this basic definition, let's explore quality control's historical evolution and development.
Evolution and History of Quality Control
The historical evolution of quality control is closely linked to the development of production processes, spanning from the earliest periods of human history to the present day. In the early days, quality control was a simple process in which master artisans inspected their products to ensure quality. In the Middle Ages, guild systems developed rules to ensure that products met specific standards and established a system for quality control. Guilds required masters to use their marks to guarantee product quality, a practice considered one of the first steps in quality control.
Industrial Revolution and Transition to Factory System
The Industrial Revolution brought fundamental changes to quality control along with massive transformations in production. As the traditional artisan system gave way to factories, the need to control product quality increased. However, during this period, quality control was limited to inspecting products at the final stage, with defective products separated only at the end of the process. This approach did not ensure product quality, as production errors were often only detected during final inspection.
The 20th Century and the Birth of Statistical Quality Control
In the early 20th Century, quality control began to be approached with scientific methods. Walter A. Shewhart introduced the concept of Statistical Process Control (SPC) and recommended statistical methods in production processes. This marked the beginning of a shift in quality control from merely inspecting the product to focusing on analyzing and improving the process. W. Edwards Deming advanced Shewhart's work, and during World War II, statistical process control was successfully applied to military production processes. These practices made quality control an indispensable part of production processes.
Japan's Quality Revolution and the Rise of TQM (Total Quality Management)
After World War II, as Japan worked to rebuild its economy, it began using quality as a competitive advantage. Training from experts like Deming and Juran on statistical quality control and process improvement led to the adoption of a “Companywide Quality Control” approach in Japan. During this period, Japanese manufacturers embraced Total Quality Management (TQM) approaches, which aimed at product quality and continuous improvement across processes and the entire organization. This philosophy contributed to Japanese products gaining worldwide recognition for quality, inspiring other countries to enhance their quality control processes.
ISO 9000 and the Emergence of Modern Quality Standards
The 1980s and 90s saw the emergence of international standards for quality management. The ISO 9000 series became a global standard by defining the fundamental requirements organizations should adopt to manage quality. This standard ensured that products and services met customer expectations while promoting continuous improvement. Today, ISO 9001 is the most widely accepted standard for quality management systems and is a crucial reference in quality management.
Lean Manufacturing and the Rise of Six Sigma
Since the late 1990s, quality control and management have evolved into more sophisticated methodologies like Lean manufacturing and Six Sigma. Lean manufacturing aims to enhance efficiency by eliminating waste, while Six Sigma emphasizes minimizing process errors and fostering continuous improvement. These approaches focus on integrating quality control into production processes and the entire organizational structure, forming the foundation of quality management strategies for many organizations today.
