ABSTRACT
Another aspect of organization which we wish to discuss separately is the need to arrange information physically so that readers can easily find their route through a mass of information that must be made available, but will not all be relevant to all readers. It is often necessary to present information which has complex interrelations, and to show how those inter-relations can lead to various outcomes. Similarly, it is often necessary to explain that various combinations of conditions can produce a particular state (perhaps a fault), and to explain that various actions must be taken according to which conditions exist.
