Business Intelligence (BI) deals with transforming raw business data into valuable information for making decisions. The goal is to improve the operation and use of large-scale, complex information systems. A number of automated BI techniques are available. These methods, however, have to be supported by user interaction to make successful business decisions. In this paper, we present a new technique for interactive business intelligence based on visualization technology, called VisImpact. The basic idea of the VisImpact technique is to visually display the relationships between the important business operation parameters and the distribution of the process flow. We have applied VisImpact in the areas of business contract analysis, business operation analysis, and fraud analysis, to show the power of the VisImpact technique for finding process flows, patterns, and trends, and for a quick identification of exceptions (outliers). Our interactive VisImpact system provides the means for an instant drilldown to a transaction record level which allows observing the evolution of business dynamics.
