What is the primary focus of Quality Control (QC)?

The primary focus of Quality Control (QC) is to identify defects before product delivery. This process involves systematic inspection and testing of products during the manufacturing stage to ensure that they meet specified quality standards and performance criteria. By detecting and addressing any issues early in the production process, organizations can prevent defective products from reaching the customer, thereby minimizing costs associated with returns, rework, and warranty claims.

In a well-implemented QC system, various tools and techniques such as statistical process control, inspections, and testing methodologies are employed to establish rigorous checks at different stages of production. This proactive approach not only enhances the quality of the final products but also builds trust with customers, as they are more likely to receive reliable and defect-free items.

Other options represent important aspects of the overall quality management process but are not the primary focus of QC. Preventing defects after delivery relates more to Quality Assurance (QA) and customer service. Enhancing product features and improving customer satisfaction are also critical components of product development and business strategy but do not directly define the essence of Quality Control practices.
