process in organization; thus, determine which business process requires more attention. The importance of those processes can be determined with Business Impact Analysis (BIA). In article, first phase of BIA is
presented – in specific, a construction of Business Impact Category Tables, Loss Levels and process weight
calculation methods. A variety of weight calculating methods is presented. Authors also present their
