Quality spiral

Fig. 1.1. The various steps of the quality assurance and quality control of the analytical laboratory can be presented on a circle, from the problem definition to the answer to the customer. When properly organised the last step leads to useful answers to the question posed by the customer. Alternatively, when the answers are not fully adequate, the analyst and the customer redefine another approach based on the results of the first circle. Due to the experience of the first investigation, this second circle has an increased chance of solving the problem. It is the start of a quality spiral (adapted from ref [10]). Fig. 1.1.

Many factors influence the set up of the quality spiral primarily structural items like equipment, infrastructure or personnel. Management, external constraints of commercial or regulatory origin, e.g. accreditation, also affect the laboratory work. They are highlighted in Figure 1.2. [Pg.4]

Fig. 1.3, The quality spiral described in Fig. 1,1 and its implementation depend on the tools available in the laboratory. These tools concern laboratory structure, personnel, management, external and internal quality assessment measures. The proper use of the available tools will lead to the development of the quality objectives (adapted from ref [10]).

Juran, identified other external and internal customers besides the end customer, necessitating a fitness of use of the interim product for subsequent internal customers illustrated by the Quality Spiral (Figure 19.3). In order to meet the demands of quality awareness, he proposed that action should be 90% substance and 10% exhortation and... [Pg.778]

Overall, the polymer of tomorrow will reach into inorganic, quasi metallic combinations on one side, and bio polymers of living tissue on the other. These will provide the widest interface in the science and the technology of matter. Both the wonderful spiral conformation of collagen, Fig. 23, and the subtle information content of its peptide components in muscle action are qualities to be sought in polymers made by people. [Pg.198]

The spiral shows actions necessary before a product or service can be introduced to the market. Each specialized department in the spiral (e.g., customer service, marketing, purchasing) is given the responsibility to cany out its assigned special function. In addition, each specialized department is also assigned a share of the responsibility of carrying out certain company-wide functions such as human relations, finance, and quality. Quality results from the intenelationship of all departments within the spiral. Juran talked about the quality function to describe activities through which the departments around the spiral can attain quality. [Pg.135]

The historical development of air quality measurements over the last 100 years has clearly influenced the monitoring strategies. These changes have not come spontaneously, but in a cycle, or rather in a spiral of related developments (Fig. 1). [Pg.288]

Hence, traditional spiral wound NF membranes require the same level of pretreatment as spiral-wound RO membranes, as well as the same flux and flow rate considerations with respect to feed water quality (see Chapters 9.9 and 9.4). [Pg.344]

TWO of their more interesting items are the Endcap Assemblies and the Blank Spirals- The Endeaps have a quality black anodized finish and feature a unique snap ring retainer for easy removal and replacement of worn out endwipes. These are far superior to the old MAC type units which require machining to remove the staked-in retaining washer. The Blank Spirals are... [Pg.153]

Twisted Tube , internal spiral fins). All are designed to impart a natural swirl component to the flow inside the tubes. Each has been proved to solve the problem of tube-side vaporization at high vapor qualities up to and including complete tube-side vaporization. [Pg.1307]
