Abstract
IT has evolved from a means of automating business process and improving business efficiency to tools for communication, collaboration, and trial and error activities in digital form. In order to enhance a series of intellectual activities conducted by an organization,i.e.,'find ,explore,measure,analyze,try,judge,implement and use,'enterprises must full use of this IT power.
In this article, I develop the model of the stages of intellectual activities, select the candidates of IT tools that can support each stage, and conduct a survey on utilization and effectiveness of these IT tools. From the survey results, I divide these IT tools into four groups such as widespread, expected, advanced, and future.
