What is a "defect" in manufacturing?

A "defect" in manufacturing specifically refers to any instance where a product does not meet predefined specifications or requirements. This definition is crucial as it highlights the importance of standards in the manufacturing process. These specifications are set to ensure that products function as intended and maintain quality and safety for consumers. When a product deviates from these standards, it can lead to issues ranging from customer dissatisfaction to safety hazards, thus impacting the reputation and financial viability of the manufacturer.

Understanding defects is essential for effective quality control and continuous improvement in manufacturing. This concept is at the heart of methodologies like Six Sigma, which focus on reducing defects to improve overall quality and efficiency in production processes. By defining a defect accurately, manufacturers can better implement procedures to identify, eliminate, and prevent defects from occurring, ultimately leading to better product compliance and customer satisfaction.
