Method, program, and system of measuring the effect of investment in an IT system

摘要

Provided is a method of measuring the effect of investment in an IT system by calculating the correlation between data on profit derived from an IT system. Various time-series data collected from a business system are classified into a profit indicator ( 104 ), a business process progress status indicator ( 105 ), and a system operation status indicator ( 106 ), and the correlation between those data is found. From the correlation, a contribution ratio indicative of the influence of the IT system operation status on the profit is calculated, and the effect of investment in the IT system is measured based on this contribution ratio.
