Ac 2007-690: Continuous Quality Control and Improvement: an Engineering Depiction of a Confounded Simple Concept

Criteria 2 and 3 of the EC 2000 have been extensively explained by professionals but engineers often find the literature very confusing because of inconsistent uses of terms and sometimes convoluted representations of the necessary actions. In this paper, the two Criteria are depicted as a dual-loop feedback control system and the terminologies interpreted in terms of process control and quality assurance. This helps remove the mystifications over an originally simple concept and makes the criteria easily understandable to engineers. Application of the representation helped faculty understand the criteria and facilitated the implementation process.
