Quiz 2: Quality Theory
Definition of theory : A theory is a "coherent group of general propositions used as principles of explanation for a class of phenomena". Importance of theory for managing quality in the supply chain : From the scientific management movement of the early twentieth century to the present focus on supply chain quality, there has been a persistent development of the quality theory. Names like Dr. Deming, W. Edwards, Dr. Juran, Philip Crosby, and others have done significant work on quality theory. The goal of quality theory is a positive outcome toward the quality of the product or service. Adoption of a philosophy towards quality improvement plays a significant role. Whether it is the Deming philosophy of continual improvement, the Ishikawa philosophy of total involvement, the Juran philosophy of a project-by-project improvement, or a contingency philosophy, launching a clear message that gives a company, a map to follow their quest for perfection. It is up to each organization to determine its own philosophy. Thus, definition of theory and its importance of managing quality in the supply chain have been discussed.
Differences between induction and deduction : If a theory has been developed by observation and description, it is understood that the theory has been evolved by the process of induction. The process of induction is valuable, but is also sensitive toward observer bias and misperception. The more general theoretical approach used by researchers is deducted. Researchers recommend a model based on previous research, and design an experiment to analysis the theoretical model with the help of deduction. This is always supported by data and statistics, and therefore, it is more realistic. Figure 1 shows Induction and Deduction reasoning. Figure 1 If I develop a theory based solely on my experiences of quality practices in business organizations, I would like my theory to be based on deduction. Since deduction helps in developing a model based on prior research, and design an experiment to test the theoretical model, while the process of induction is sensitive toward observer bias and misperception. Thus, Differences between induction and deduction and uses of theory in business organizations have been discussed.
Unified theory of quality management and its evolution : Einstein worked many years on unified theory in physics with no satisfactory result. Since then it has been a question about the existence of a unified theory. And many questions related to this theory are under consideration. Queries like, what would be the implications, if there was a unified theory of quality management? Whether it was justified for different situations are unanswered. As per my belief, I think it is not possible to develop a unified theory of quality management as wished, just as there cannot be the same medicine for all diseases. Thus, Unified theory of quality management and its development have been discussed.
