It is assumed that BI may support decision making on all levels of management regardless of the level of their structuralisation (Olszak, & Ziemba, 2003). On the strategic level, BI makes it possible to set objectives precisely and to follow realisation of such established objectives. BI allows for performing different comparative reports, e.g. on historical results, profitability of particular offers, effectiveness of distribution channels along with carrying out simulations of development or forecasting future results on the basis of some assumptions.
