Which of the following is NOT a component of a quality control system?

• A. Reviewing processes regularly
• B. Defining standards
• C. Making random decisions
• D. Implementing checks

Answer: (C)

A quality control system is designed to ensure that products or services meet specified standards and are consistent over time. Key components of such a system typically include establishing clear standards, regularly reviewing and assessing processes, and implementing checks to ensure compliance with those standards.

Making random decisions does not align with the principles of quality control. Instead of fostering systematic improvement and consistency, random decisions can lead to unpredictability and inconsistency in quality, which is counterproductive to the goals of quality management. Effective quality control relies on data-driven decision-making and standardized protocols to manage production and maintain quality levels; randomness undermines this approach.

Hence, the answer accurately identifies a choice that does not belong to a well-defined quality control framework.
