It is important to note that the evolution and development of management studies dated back to earlier civilization. So much information on management theory and practice exists today that it is difficult, if not impossible to keep abreast of all of it.
Scholars from many fields- including psychology, sociology, philosophy, history etc. have at one time or another been interested in management and have contributed to the study of management. With each new perspective have come new questions and assumptions, new research techniques and new conceptual framework.
