Cost of non-conformance

This first example applies to UK industry in general. The turnover for UK manufacturing industry was in the order of 150 billion in 1990 (Smith, 1990). If the total quality cost for a business was likely to be somewhere in the region of 20%, with failure costs at approximately 50% of the total, it is likely that about 15 billion was wasted in defects and failures. A 10% improvement in failure costs would have released an estimated 1.5 billion into the economy. IBM, the computer manufacturer, estimated that they were losing about 5.6 billion in 1986 owing to costs of non-conformance and its failure to meet quality standards set for its products and... 

Tolerance stack analysis - Tolerances on components that are assembled together to achieve an overall design tolerance across an assembly can be individually analysed, their potential variability predicted and their combined effect on the overall conformance determined. The analysis can be used to optimize the design through the explorations of alternative tolerances, processes and materials with the goal of minimizing the costs of non-conformance. This topic is discussed in depth in Chapter 3.

The losses that companies can face are influenced by many factors including market sector, sales turnover and product liability history. It is not easy to make a satisfactory estimate of the product liability costs associated with quality of non-conformance, and... 

To improve customer satisfaction and business competitiveness, companies need to reduce the levels of non-conformance and attendant failure costs associated with poor product design and development. Attention needs to be focused on the quality and reliability of the design as early as possible in the product development process. This can be achieved by understanding the potential for variability in design parameters and the likely failure consequences in order to reduce the overall risk. The effective use of tools and techniques for designing for quality and reliability can provide this necessary understanding to reduce failure costs. 

The Standard considers that an effective quality system should comprise management responsibility quality system principles quality system audits quality/cost considerations raw material quality control inspection and testing control of non-conforming product handling, storage, packaging and delivery after sales service quality documentation and records personnel training product safety and liability and statistical data/analyses. 

It is clear that hydrophobic interactions are essential to the formation of the native structure of globular proteins. Again, thermodynamic studies [20] on such systems plus the analysis of protein crystal structures [30] are strong evidence for the essential role of these hydrophobic interactions. Globular proteins in their native conformation do have their hydrophobic atoms on the inside , away from the water, and the addition of non-aqueous solvents to the water tends to destabilize this structure, since the exposure of non-polar groups is not so energetically costly in e.g., mixed alcohol/water solvents as it is in pure water. 

Group 4. These are the remaining items, where inspection is carried out on a basis of economic evaluation, considering the selected supplier s reputation and facilities, the availability and credibility of conformance certificates, the consequences of accepting non-compliant items, and the cost of inspection. 

The traditional service level agreements (SLAs) where suppliers are penalized for non-conformance of time, cost and specifications are not appropriate for procnrement strategy based on partnerships. The traditional procurement thinking should be revisited and there should be a move where a client organization is actively managing the canse of risk or non-conformance and not the... 

Cost of poor quality (COPQ) The cost of poor quality is made up of costs arising from internal faUnres, external failures, appraisal, prevention and lost opportunity costs. In other words all the costs that arise from non-conformance to a standard.
