Quality Circle: A quality improvement or self-improvement task force composed of a small number of employees (10 or less) and their supervisors. Quality circles originated in Japan, where they are called quality control circles. Quality: A subjective term for which each person or industry has its own definition. In technical use, quality can have two meanings: (1) the characteristics of a product or service that affect its ability to satisfy stated or implied needs; 2) a product or service free from defects. According to Joseph Juran, quality means “ease of use”; According to Philip Crosby, this means “compliance with requirements”. Employability has become the fashionable means of harnessing the desire for perfection. The ultimate measure of perfection, “zero defects,” may be a great definition of quality, but the deadly risks may be completely unnecessary. If the product does not correspond to its purpose, its perfection is irrelevant. Another approach to defining quality comes from Joseph Juran. He was one of many management theorists working in Japan in the 1950s. Juran defined quality as “usability”: what do you think? Is quality better considered “compliance with requirements”? Or “conviviality”? Or maybe something completely different? Please share your thoughts in the comments below.
Quality loss function: A parabolic approximation of the quality loss that occurs when a quality characteristic deviates from its target value. The quality loss function is expressed in monetary units: the cost of deviation from the target increases quadratically as the quality characteristic moves away from the target. The formula used to calculate the quality loss function depends on the type of quality characteristic used. The quality loss function was first introduced in this form by Genichi Taguchi. This approach provides a model for determining the specification of a quality product or service. It is also development-oriented, as it recognizes that objectives can change over time, requiring a constant reassessment of the suitability of the specification. I never really decided on Crosby`s “compliance with requirements” approach (even before Agile came along) because there was never a way to make sure the requirements were correct. Saying something like the old Microsoft Bob was of high quality because it corresponded to a poorly thought out requirements document never seemed right to me. Quality is mentioned a lot in discussions about Agile.
So perhaps it would be useful to clarify my definition of quality. Of course, others have thought more deeply about quality than I have. Therefore, I will not give a new definition of quality here. But I will explain what I think about quality. QEDS Standards Group: United States The Standards Group for Quality, Environment, Reliability and Statistics is composed of members and leaders of organizations concerned with the development and effective implementation of general and sectoral standards for quality control, assurance and management. Environmental management systems and audit, reliability and application of statistical methods. Quality assurance/quality control (QA/QC): Two terms that have many interpretations due to the multiple definitions of the words “assurance” and “control”. For example, “insurance” may mean the act of trust, the state of certainty, or the act of insuring; “Control” can mean an assessment to indicate the necessary corrective responses, the act of leadership, or the state of a process in which variability is due to a constant system of random causes. (For a detailed explanation of the different definitions, see ANSI/ISO/ASQ A3534-2, Statistics – Vocabulary and symbols – Statistical quality control.) One of the definitions of quality assurance is all planned and systematic activities that are carried out within the framework of the quality system and that clearly create confidence that a product or service meets the quality requirements. A definition of quality control is: the operational techniques and activities used to meet quality requirements.
However, the terms “quality assurance” and “quality control” are often used interchangeably and refer to measures taken to ensure the quality of a product, service or process. Vlãsceanu et al., (2007, pp. 71-72) define quality as fitness for purpose in terms of compliance with industry standards: one of the possible criteria for determining whether or not a unit meets quality, measured against what is considered the unit`s purpose. Quality Function Deployment (QFD): A structured method in which customer needs or expectations are translated into appropriate technical requirements for each phase of product development and production. The QFD process is often referred to as listening to the voice of the customer. means that the “goal” of a project must be precisely defined and that resources should not be wasted trying to produce a product of better quality than necessary. Another way to say this is that quality is “meeting customer requirements and nothing more”. Who is the “customer” in the case of course material development in higher education? Is it the student who wants an effective product at a high level? Or is it the project sponsor who wants to have a lot of products in a short period of time within clearly defined cost limits? While “ease of use” is designed to be simple, it is misleading because it raises the question of who is doing the purpose to and how relevance is evaluated. Fit for purpose provides two alternative priorities for specifying the objective.
