User acceptance

Technical and Business Issues. In general, the successflil appHcation of any technology is dependent on both technical and business issues. For knowledge-based systems, six critical issues are problem identification, user acceptance, measurement of impact, appropriateness, feasibHity, and cost.

If the oxygen content of the contaminated air is deficient (refer to page 72), breathing apparatus is essential. The degree of protection required is determined by the level of contamination, the hygiene standard for the contaminant(s), the efficiency of any filter or adsorber available, and the efficiency with which the facepiece of the device seals to the user s face (this is reduced by beards, spectacles etc.). The level of comfort and user acceptability are further considerations. 

The choice of access-control technology depends upon the level of security to be achieved, number of users and traffic at peak periods, etc. Proper design of the system is critical to its performance (and user acceptance), and reliability and expert advice should be obtained from equipment manufacturers and system installers.

For computer systems that do not require formal validation, at a minimum, user acceptance testing should be performed. This User Acceptance Testing should be outlined in a facility SOP, where the system is tested and assured to perform in the desired function effectively. The User Acceptance should be documented, and the system should be released for specific uses. 

Cmcial documentation needed in the development phase includes end-user manuals, a unit test summary report, a user acceptance test plan, results of the database design, results and methods employed in the source code evaluations, and a trace-ability analysis. A source code traceability analysis verifies that all code is linked to established specifications and established test procedures. 

As has been the case for centuries, many people continue to rely on natural products for the treatment of a host of physical and mental problems ranging from the common cold and rashes to cancer and loss of memory. Scientific evidence for the efficacy of many of these products is weak, hut users accept cultural, historical, religious, quasi-medical, and other justifications for their use. The sale of dietary supplements in the United States alone nearly doubled in less than a decade, growing from 8.8 billion in 1994 to an estimated 15.7 billion in 2000. Clearly, whatever disadvantages they may have in terms of efficacy and safety, natural products will continue to constitute a major portion of the drug market in the United States and other countries around the world.
