Which process helps manufacturers in identifying product defects during production?

Quality control is the process that assists manufacturers in identifying product defects during production. It involves a series of systematic procedures and evaluations designed to monitor and ensure the quality of the products being manufactured. This can include various checks and tests at different stages of the production process to ensure that items meet predetermined standards and specifications.

The effectiveness of quality control lies in its proactive approach, enabling manufacturers to catch defects before products leave the production line. This helps in reducing waste, lowering costs, and improving customer satisfaction by ensuring that only products that meet quality standards reach the market. By incorporating various tools and techniques, quality control can reliably detect deviations from quality standards, allowing for immediate corrective actions.

In contrast, marketing research focuses on understanding market needs and consumer behavior, while sales training is aimed at developing the skills of sales personnel. Root cause analysis, while important for problem-solving and understanding the underlying causes of defects, typically comes into play after an issue has been identified rather than during the ongoing process of production. Thus, quality control is the most effective process for identifying product defects as they occur within the production cycle.
