Which of the following is NOT a component of the Quality Control process?

In a Quality Control (QC) process, the primary components focus on ensuring that materials and processes meet specified standards and quality criteria. Sampling involves selecting a portion of material for testing to ascertain that it is representative of the whole batch. Testing refers to the various methods used to assess the properties and quality of the materials being evaluated. Evaluation is the stage where the results of sampling and testing are analyzed to determine compliance with desired specifications and standards.

Staff promotions, while essential for workforce motivation and development within an organization, do not play a direct role in the QC process as it pertains to assessing material quality. The QC process is primarily concerned with methodologies and actions that directly influence the measurement and assurance of quality, rather than organizational structure or personnel management. Thus, it is clear that staff promotions do not align with the technical components that constitute the quality control framework.
