Paper Title
Examining levels and complexity of Management theories and schools of thought

Abstract
In this paper, we discusses about concept of ôlevel" in organization and management theories. Then, introducing a framework for classification theory levels and argues that data measurement levels and their analysis should be fit with theory level. Next, survey the concept of "complexity level" in theory and with describing a framework for the concept, at first classifies the complexity levels of theories and then by applying some valid theoretical frameworks classifies the complexity levels of management schools of thought. Finally, we present the multilevel and metaparadigmatic theories and their advantages. Keywords- Theory, Theory Level, Theory Complexity, Metaparadigm
