Conventionally, there is a technique to conduct a cause analysis in which a single evaluation axis, such as a performance time, is used to configure a problem point network. However, in particular, in a system to visualize a management problem in which problems are intricately-intertwined with one another, information on multiple evaluation axes, collected from a business system, are utilized, and units are different for respective evaluation axes. Therefore, it is difficult to simply specify a cause of problem occurrence. In view of this situation, an object of the present invention is to extract and present factor which has a significant influence on the problem occurrence. The present invention is directed to an apparatus which stores causal relation information specifying the causal relation and the relation level between the indexes, business goal achievement level information, and an influence level of the causal relation, calculates the influence level by using the business goal achievement level information and the relation level of the causal relation, specifies as the causal index the index having a large influence, and generates screen information for displaying a graph and/or table relating to the causal index.
