Neo classical theory is a combination of formal and informal organization. It is based on human view of organization. This theory contains flat structure of organization, decentralization and informal organization. Modern organization theory was developed in early 1960s. It takes an organization as an adaptive, dynamic and open system.
I am an organizational sociologist, trained in economic sociology and structural contingency theory at the University of Wisconsin—Madison. For more than two decades, I have benefitted from the teachings and friendships of Michael Aiken, Eric Olin Wright, and Richard Schoenherr, who died prematurely in 1995.
