Which aspect of quality control involves systematic and planned actions?

Quality assurance is a fundamental component in maintaining high standards in processes and outputs within various fields, including healthcare and diagnostics. This aspect focuses on systematic and planned actions taken to ensure that services and products meet established requirements and standards consistently.

Quality assurance entails the development and implementation of processes designed to prevent errors and defects. It involves setting quality objectives, establishing processes to achieve those objectives, and monitoring performance against them over time. By emphasizing planned actions, quality assurance aims to create a robust framework that supports continual adherence to quality standards, ultimately enhancing the reliability and safety of healthcare practices.

In contrast, the other concepts such as quality administration, quality improvement, and quality evaluation each emphasize different processes related to quality but do not specifically focus on the systematic and planned actions characteristic of quality assurance. Quality administration relates more to the organizational aspects of managing quality, quality improvement focuses on increasing quality through iterative processes and feedback, and quality evaluation generally pertains to assessing performance against standards rather than ensuring consistent quality through planned actions.
