Quality control is made up of those activities and techniques used to achieve and maintain a high
standard of quality in a transformation process at reduced cost. They may include systematic
inspection of inputs and outputs at various stages in their transformation to ensure that acceptable
tolerances are not being exceeded. They may also involve a statistical analysis of data produced by the
sampling (particularly in line production), benchmarking, continuous improvement (CI) and supplier
partnering. In this case, in traditional organizations, management has to balance the cost incurred
against the customers’ goodwill. Quality control is also concerned with finding and eliminating the
causes of quality problems.
