The only real source of energy in organisations Human inputs form a critical part in the conversion process i.e. conversion of input into output. The utilisation of human energy and potential in organisational processes can be seen to be determined by four factors.

Structural authority where management decisions are made.
Individuals who operationalise these decisions.
External realities such as change in technology, market trends and so on.
Internal realities of the organisation – broadly its systems, practices and technology.

The nature of the overlap or convergence between these four factors determines the way in which the organisation is energised by its people. The nature of the overlap / convergence has a unique quality to it. It can be conceptualised as four envelops each containing a specific set of processes.
