Based on the internal logic of human nature throughout the whole history of management thought, I can prove a natural and flexible “three-tier management”, and at the same time make a roadmap of connection among thought leaders like Ernst Engel, Abraham Maslow, Clayton Alderfer, Frederick Taylor, Henri Fayol, Elton Mayo, Douglas McGregor, and Joseph Schumpeter.
There are some differences between theory X and theory Y and three-tier management.
How to meet effectively and efficiently employees’ needs from the perspective of management model or system?
What is the natural human nature (and by natural, I mean the human nature is not influenced by culture, religion and so on)?
Here the natural human nature basically refers to Maslow‘s hierarchy of needs theory (HoN), or Alderfer's Existence, Relatedness and Growth Theory (ERG). In ERG, Alderfer compressed Maslow's HoN from five to three. For the sake of convenience, I adopt the latter.
