Abstract
Professor Hiroaki Wakuta, former president of Japan Society for the Study of Office Automation,
contributed greatly to founding the JSSOA (currently, Japan Society of Information and Management, JSIM). He has published more than forty papers in the Journal of JSSOA; his papers cover a broad range of topics such as OA theory, management theory, and management education. This study surveys his major papers to review his theoretical framework and original ideas that are based on the system theory. He always had an interest in the relationship between subsystems and between subsystems and the whole system. Current researchers still have a lot to learn from his active attitude toward research.
