Hi
In my opinion, you must focus on functional aspects of HR and the various theories under each function, which bring about varied interpretations and perspectives to the inputs that are required to appreciate the most important asset of an organization viz. Human Resources.
Maslows hierarchy of needs gives an understanding of human nature, McGregor’s Theory X and Theory Y focus on basic style of management, Hezerbergs two factor theory draws attention to the complexities of human motivation. You can take a couple of theories in each and draw attention to the fact that each theory has a basis but draws varied conclusions / interpretations. Management has to amalgamate these theories when they draw up a HRM strategy.
Trust, I have given you at least a broad roadmap to start off with.
