Abstract

Describes phase 2 of the project. Aimed to develop the prototype CIDA further, incorporating the recommendations made by the evaluators of the system during phase 1 and to undertake additional evaluation once changes had been made. Specific objectives were: to enhance the user interface of the prototype in accordance with evaluators' recommendations; to refine the system advice; to field test the system in anorganization where online company information searching is frequently undertaken; and to compare the accuracy and efficiency of the prototype to that of manual directories giving details of online company databases
