The use of CA has proved to be beneficial for companies introducing a new product, when an opportunity exists to use new processes/technologies or when design rules are not widely known. Design conformance problems can be systematically addressed, with potential benefits, including reduced failure costs, shorter product development times and improved supplier dialogue. A number of detailed case studies are used to demonstrate its application at many different levels. 

Hillary, Ruth, ed. ISO 14001 Case Studies and Practical Experiences. Sheffield, U.K. The Network for Environmental Management, Greenleaf Publishing, 2000. - Contains case studies that provide experiences of companies and what certifiers look for when they visit firms. Highlights ISO 14001 s strengths and weaknesses. Analyzes environmental and economic performance improvements under ISO 14001. 

Nowadays many companies have adopted a policy of continuous improvement of working conditions. Therefore, it is desirable to create target levels for those who want to pursue more efficient control by applying the best available control technologies. There are also endeavors to create optimal working conditions in order to improve the performance and the innovativeness of a staff, and hence enhance productivity. A series of laboratory and case studies show that employee productivity is higher when the work environment is appropriate for the tasks being done.- Such efforts are typical in the advanced sector of industry. One can say that there is a transition from blue-collar to white-collar work. ... 

The case study that follows is reproduced with permission from the Chemical Manufacturers Association publication Improving Human Performance in the Chemical Industry A Manager s Guide, Lorenzo (1990). Another CPI case study that uses THERP is documented in Banks and Wells (1992). 

The purpose of this chapter is to show that improvements in safety, quality, and productivity are possible by applying some of the ideas and techniques described in this book. The fact that error reduction approaches have not yet been widely adopted in the CPI, together with questions of confidentiality, has meant that it has not been possible to provide examples of all the techniques described in the book. However, the examples provided in this chapter illustrate some of the most generally useful qualitative techniques. Case studies of quantitative techniques are provided separately in the quantification section (Chapter 5). The first two case studies illustrate the use of incident analysis techniques (Chapter 6). 

A case study on the operational improvement of a plasma etching unit in microelectronics fabrication ends the section. This case study illustrates that if similar preference structures are used in both types of formulation, identical final solutions are found when either categorical or continuous performance evaluation modes are employed.

Dermal Effects. Some of the people in Woburn, Massachusetts, who had been chronically exposed to trace amounts of trichloroethylene and other substances in the drinking water reported skin lesions (Byers et al. 1988). These were maculopapular rashes that were said to occur approximately twice yearly and lasted 2-4 weeks. These skin conditions generally ceased 1-2 years after cessation of exposure to contaminated water. The limitations of this study are discussed in Section 2.2.2.8. A case study was published of a 63-year-old rural South Carolina woman exposed to trichloroethylene and other chlorinated hydrocarbons in her well water, who developed diffuse fascitis, although her husband did not (Waller et al. 1994). The level of trichloroethylene measured in the well water was 19 mg/L. Substitution of bottled water for drinking resulted in improved symptoms.

Finally, the coupling of SLCA, further evaluation criteria and multi-objective optimisation are demonstrated with the help of a second case study dealing with the improvement of synthesis strategies for ionic liquids (see Section 7.5). 

The case study described here shows that emissions of chemicals, including substances that might be considered as additives in the printed matter life cycle, may contribute significantly to the LCA impact profile. In order to increase the reliability of this result, confirmation, by use of newer and improved LCIA methodology and updated LCI data for the background processes, are desirable. Newer LCIA methodology has actually been used in other LCA studies on printed... 

In order to improve the comprehensiveness of the basis for the assessment, including the coverage of chemical emissions, future LCA case studies on printed matter need to include at least the following issues ...
