Definition of Management Model
Jaap de Jonge, Editor, Netherlands
I think your realization is correct in that there is no universally accepted definition of the term 'management model'. If you think about it, both the word MANAGEMENT and the word MODEL can have quite different meanings in various parts of the world.
However broadly speaking, a 'model' is a simplified way to analyze, describe, or deal with a more complex reality. A model is similar, but not equal, to a theory, method, approach, tool, or instrument.
Likewise, broadly speaking management is the science of organizing and leading organizations (profit and non-profit). For more info on management, our Fayol and Gülick knowledge centers are a good start. 15-2-2017
