ABSTRACT
According to Shute et al. (2000), a vast number of appropriately skilled personnel are required if a CTA is to be conduced properly. A typical CTA would normally require the provision of a multidisciplinary team over a lengthy period of time. Of course it is often difficult to assemble such multidisciplinary teams, let alone gather them together at one location for any period of time. The problems of cost and personnel shortages ensure that the process of merely getting to the stage where CTA analysis can actually commence is a very difficult one. As a result, the problems associated with the cost, time invested, and personnel required may far outweigh the benefits associated with conducting the CTA in the first place. It appears that organizations may be put off conducting a CTA by the cost-effectiveness issue alone, let alone the other problems associated with it. This is a big problem and one that could threaten the future usage of CTA techniques.
