UPDM — 8.5.10.3 Description

An Effect is an action that brings about a change in the state of something. The event that initiates the action is a Trigger.
The action is the result of an OperationalTask. An Effect is caused by collaborating OperationalNodes that bring about the
Effect as a result of their OperationalTasks. The collaboration, an OperationalCapabilityRealization, can be described in
terms of the Effect that it has. This Effect can be observed in an EventTrace from the perspective of the sequence of OperationalTasks. It can be seen in a StateTrace as a transition that CausesEffect showing the Trigger, the Effect, and the
desired ResultOfEffect, the end state. The OperationalActivity can show the Events that are Triggered and the receiving
Action that includes the OperationalTask in callOperationActions.
An Effect is the central player in all of these scenarios unifying the OperationalCapabilityRealization with the Effect,
viewed from the perspective of the collaborating OperationalNodes, the Triggers, States, and Activities."
