The availability of advanced techniques provides job satisfaction for analytical staff and the use of such techniques provides the information needed by management to maintain a competitive edge. The use of these techniques is usually by specialist and highly qualified staff although we would stress that this is not necessarily so. These staff need to concentrate their efforts on the analysis and interpretation of results not on programming. We have therefore made our systems as easy to use as possible and TSAM for example can be learned in as little as one day. The interactive nature of our service makes possible the rapid evaluation of alternatives and re-runs with new data. This simplifies tasks and improves the probability of optimum results. Clear presentation of these results is important and we have therefore provided reporting and graphics facilities as built in options.
