An Implementation Event is a behaviour element that denotes a state change related to implementation or migration.
Work Packages may be triggered or interrupted by an Implementation Event. Also, work packages may raise events that trigger other behaviour. Unlike a Work Package, an event is instantaneous: it does not have duration.
An Implementation Event may have a time attribute that denotes the moment or moments at which the event happens.
Implementation Events access Deliverables to fulfil project objectives.
An Implementation Event may trigger or be triggered (raised) by a Work Package or a Plateau. An Implementation Event may access a Deliverable and may be composed of other Implementation Events.
An Implementation Event may be associated with any core element; e.g., to indicate a lifecycle state change.
The name of an Implementation Event should preferably be a verb in the perfect tense.
