===The Semantics of Arrows===

For activities:^{_{Superscript text}}

* Inputs enter from the left and represent data''' r^{Superscript text}or consumables that are needed by the activity.

* Outputs exit from the right and represent data or products that are produced by the activity.

* Controls enter from the top and represent commands which influence the execution of an activity but are not consumed.

* Mechanisms identify the means, components or tools used to accomplish the activity. Represents allocation of activities.

For data: ==

* Inputs are activities that produce the data.

* Outputs consume the data.
