Which of the following is NOT one of the three components of the quality trilogy?

The three components of the quality trilogy, as defined by Joseph Juran, are quality planning, quality control, and quality improvement. Each of these components plays a critical role in ensuring that organizations can deliver high-quality products and services.

Quality planning involves determining the quality standards and goals that an organization seeks to achieve and establishing processes and systems to meet those standards. Quality control refers to the processes that monitor ongoing operations to ensure that they meet the established quality standards. Quality improvement focuses on ongoing efforts to enhance processes and outcomes over time.

In this context, quality assurance is not one of the three core components of the quality trilogy. While quality assurance plays a significant role in helping organizations achieve and maintain high-quality standards, it is not explicitly listed as one of the trilogy components. Quality assurance typically involves systematic activities that ensure quality requirements are met throughout the processes rather than being a standalone pillar like the others in the trilogy.
