“Five major approaches to the definition of quality can be identified: (1) the transcendent approach of philosophy; (2) the product-based approach of economics; (3) the user-based approach of economics, marketing, and operations management; and (4) the manufacturing-based and (5) value-based approaches of operations management. Table 1 presents representative examples of each approach.”

“The System of Profound Knowledge” “The System of Profound Knowledge (SoPK) is the culmination of Dr. W. Edwards Deming’s lifelong work. It is an effective theory of management that provides a framework of thought and action for any leader wishing to transform and create a thriving organization, with the aim for everybody to win. By management appropriately applying the principles and practices of SoPK, a business can simultaneously reduce costs through reducing waste, rework, staff attrition and litigation, while increasing quality, customer loyalty, worker satisfaction and, ultimately, profitability. SoPK ties together Dr. Deming’s seminal theories and teachings on quality, management and leadership into four interrelated areas: appreciation for a system, knowledge of variation, theory of knowledge and psychology.”

“The term Rework refers to the repetition of a process to bring a product or service into conformance with its original requirements. It is usually done after the completion of a product or service and includes all the necessary actions to transform the products that don’t follow the specified qualifications into products that do (Owen and Blumenfeld, 2007; Flapper et al., 2002). Additional to rework there are two related concepts: Repair and Scrap.”
