What concept in TQM focuses on preventing defects rather than detecting them?

The concept that emphasizes preventing defects rather than simply detecting them is quality assurance. Quality assurance focuses on the processes and systems in place to ensure that quality standards are met throughout the entire production process, rather than only inspecting final products after they have been made. By instituting quality assurance, organizations aim to build quality into their processes, resulting in fewer defects and less need for rework or correction later in the cycle.

Quality assurance involves proactive measures such as developing quality management processes, training employees, and continually improving operations. This approach helps organizations establish a culture of quality that reduces the chances of defects occurring in the first place, thus aligning perfectly with the principle of preventing issues before they happen.

In contrast, other concepts like quality control primarily focus on identifying and fixing defects after they occur, corrective action addresses issues post-factum (when defects arise), and preventative maintenance, while important, relates specifically to the upkeep and functioning of equipment rather than the overall quality of products being produced.
