There has been a lot of controversy about whether the return on IT (Information Technology) is adequate. While the number of articles on IT evaluation has been substantial, limited attention has been given to the value of an intangible benefit. This paper aims to suggest an approach to putting a financial estimate on the intangible benefit of IT applications. The authors' chose a sample system for the evaluation and utilized the contingent valuation method to quantitatively measure the intangible value. Then, a valuation and analysis model were suggested for the quantitative valuation of the intangible benefit from IT adoption.
