Abstract
The stakeholders of IT management of companies include not only the demand side (IT
user companies) but also the supply side (IT vendor companies). We conducted five studies over
ten years researching IT management effectiveness and software engineering excellence from the
viewpoint of both the demand side and the supply side. In this paper, we summarize the results of
our research, including causal relationships related to management behavior, operations and business
performance. Also, we consider science for society in a future-oriented manner in order to sublate
the results of social research towards society’s intellectual caliber.
