What concept is utilized to monitor and adjust processes in Juran's framework?

In Juran's framework, the concept utilized to monitor and adjust processes is quality control. Quality control focuses on the operational techniques and activities aimed at fulfilling quality requirements. It involves the ongoing measurement and monitoring of processes to ensure they are functioning as intended and producing products or services that meet established quality standards.

Quality control helps detect deviations from desired performance levels and allows for timely corrective actions to maintain quality. This is essential for maintaining consistency in output and ensuring customer satisfaction. By implementing quality control measures, organizations can identify issues, reduce variability, and enhance process stability over time.

While quality assurance, quality improvement, and quality planning are critical components of maintaining overall quality within an organization, they serve different purposes. Quality assurance is more about ensuring that the processes are adequately defined and followed, quality improvement focuses on proactively enhancing processes for better performance, and quality planning involves setting quality goals and determining the necessary actions to achieve them. Thus, quality control is crucial for the real-time management of processes, making it the correct concept in this context.
