Quality of conformance

Variation is an obvious measure for quality of conformance, but it must be associated with the requirements set by the specification to be of value at the design stage. Unfortunately, difficulty exists in finding the exact relationship between product tolerance and variability. Approximate relationships can be found by using process capability indices, quality metrics which are interrelated with manufacturing cost and tolerance (Lin et al., 1997). ... 

Measures to minimize safety problems must be initiated at the start of the life cycle of any product, but too often determinations of criticality are left to production or quality control personnel who may have an incomplete knowledge of which items are safety critical (Hammer, 1980). Any potential non-conformity that occurs with a severity sufficient to cause a product or service not to satisfy intended normal or reasonably foreseeable usage requirements is termed a defect (Kutz, 1986). The optimum defect level will vary according to the application, where the more severe the consequences of failure the higher the quality of conformance needs to be. 

The type of compressor selected sets the quality of design. The API-based compressor is generally regarded as a higher quality than a catalog blower. Most of the chapter to this point has attempted to emphasize the many factors involved in design. Quality of conformance is a measure of how well the compressor met the specification. One of these measures is the achievement of the desired run time. Another measure is the inspection for conformance of the parts to the drawings. 

Quality of conformance is the extent to which the product or service conforms to the design standard. The design has to be faithfully reproduced in the product or service. 

Quality, service, cost, and technology are not mutually exclusive. One can t distinguish between a quality improvement and a service or technology improvement. It was necessary only to mention quality and cost, as an improvement in service must be an improvement in either the quality or cost of the service - all other factors come within the definition of quality. Improvements in technology are also improvements in quality or cost. Such improvements may improve the quality of design, quality of conformance, or quality of use (see Part 1 Chapter 1 under Quality parameters) or may cause a reduction in cost while not providing any change in product or service characteristics. 

Quality Assurance, the responsibility of the quality assurance unit, is the nitpicking, but totally necessary, job of determining the quality of conformance to regulations established by managers and their chemists and is done via audits and inspections. To develop a thorough quality program both quality control... 

Quality of conformance (how well the product conforms to the specifications required) is influenced by a number of factors, including the choice of manufacturing processes, the training and supervision of the workforce, the types of process controls, tests, and inspection activities that are employed, the extent to which these procedures are followed, and the motivation of the workforce to achieve quality. 

Satisfaction is not to be confused with dimensions of quality such as 1) quality of conformance or 2) quality of design. Quality of conformance is the consistency of how the product is manufactured or the service is delivered. For example, pharmaceutical tablets are manufactured to fit within FDA standards for dissolution. Each batch is tested to determine if tablets within that batch fit standards. Quality of design is how well the product or service meets the needs of consumers or how well the product or service compares with those of competitors in the eyes of the consumer. In the pharmaceutical tablet example, the manufacturer would evaluate the quality of design by comparing the clinical outcomes provided by the product to the desired outcomes of the patients. Such factors as returning to normal health or avoiding side effects would be used in the evaluation of quality of... 

From this definition it is obvious that packaging components come within the scope of validation (via the material route). In the context of the earlier review of quality of design and quality of conformance, it may seem that the validation concept does not offer a great deal of additional confidence. However, this would ignore the recent history of validation and its expansion into qualification. 

Pharmaceutical products must meet special quality standards in view of their application. The development, manufacture and packaging, and control must therefore be carried out in such a manner that the quality is adequately preserved. To this end, it is necessary to develop an integrated quality assurance system. Such a Quality Assurance System covers the quality of design as well as the quality of the product as it is marketed (quality of conformity). 

Jorgensen and co-workers have developed an efficient method of sampling a QM/MM Hamiltonian that enables them to increase the quality of conformational... 

There has been significant recent development in the application of QM/MM methods for computational enzymology, whereby both the detail of the physical model of the enzyme system, and the quality of conformational sampling have improved dramatically. This has now led to computational simulations of certain enzyme systems that are sufficiently accurate to allow direct comparison with experiment. Computer simulations have now reached a level of accuracy, for some systems, that permits their use as a means of verifying or dismissing proposed... 

Quality management. Providing experienced professionals to help suppliers navigate the differences between quality of design and quality of conformance to ensure the receipt of quality materials. 

Quality—Conformance to requirements or fitness for use. Quality can be defined through five principal approaches (1) Transcendent quality is an ideal, a condition of excellence. (2) Product-based quality is based on a product attribute. (3) User-based quality is fitness for use. (4) Manufacturing-based quality is conformance to requirements. (5) Value-based quality is the degree of excellence at an acceptable price. Also, quality has two major components (1) quality of conformance—quality is defined by the absence of defects, and (2) quality of design—quality is measured by the degree of customer satisfaction with a product s characteristics and features. 

Value-based quality is the degree of excellence at an acceptable price. Also, quality has two major components (1) quality of conformance—quality is defined by the absence of defects, and (2) quality of design—quality is measured by the degree of customer satisfaction with a product s characteristics and features. 

Quality consists of two elements quality of conformance (have we met specifications ) and quality of design (are the specifications correct ). In the case of the behaviour-based approach, such specifications are expressed in terms of specific, observable and measurablebehaviours.Ratherthan being a somewhat abstract truism, quality is, in effect, defined for sub-units of the overall process in terms of specific units of behaviour. The previous use of this approach for safety improvement suggests that it would work equally well for quality of conformance. Quality of design, however, is dependent on increasing levels of inter-departmental communication and the establishment of an internal quality model. Therefore, the approach should facilitate both a team model and an internal customer approach to quality improvement. Before this structure is discussed in detail, it is important to consider the issue of gaining commitment to a quality improvement process.
