Abstract
This paper deals with the investigation of theoretical contributions of research for Management Information Systems (MIS) by employing a comparative studies focusing on engineering methodologies for information science. At first, we summarize the origin and the state of the arts of MIS, and discuss the development of information engineering in Japan by focusing on their important role for supply of human resources, and also their limitations. Then we select three dominant technical journals in the USA to extract key words from papers in these journals. The frequencies of key words in papers are used to compare the trends of researches between MIS and OR, MS. Finally, we discuss the important tasks and novel fields of MIS by considering the overall commoditization of information technology.
