The stage of exploration and discovery of new informational needs is of critical importance for the whole cycle of building any BI. Implemented BI environment casts new light on the role of information and competencies in an enterprise and on business relations and interdependencies. At this stage, new informational needs emerge and new methods of information management are created. Using notions of iterative designing and rapid application development (RAD), it is possible
to observe that the BI environment obtained is a prototype that should serve as the basis for evaluation and commencement of a new cycle of building a BI application (Dresner et al., 2002). The exploration and discovery stage requires remarkable co-operation of representatives of IT departments with a centre for knowledge management along with end users whose all innovativeness and willingness to experiment with data are of much importance.
