Context diagram

The 'context' of any situation is the external environment in which it exists. Like a ship on the seas, the captain ignores the elements at his (or her!) peril. Whilst the ship is self-contained, it is intimately connected to its context.

In process terms, the context contains other processes that provide inputs and outputs to and from the process in question. Taking a business view, there are also forces from such as competitive and environmental domains.
