BACM11 — Determine of the triggers association between Outcome and ValueStreamStage is needed.

The addition of entryCriteria linking Outcome to ValueStreamStage appears to eliminate the need for the triggers association, since triggering is one of the functions subsumed by the entryCriteria relation and would imply the existence of an identical entryCriteria relation.

The addition of entry and exit criteria in resolving BACM11-3 eliminates the need for this association that essentially duplicates the semantic conditions of entryCriteria. As entryCriteria and exitCriteria are both <<class>> stereotyped associations, an architect may create specific properties for them when creating instances.
Note that the BIZBOK describes triggering by stakeholder (i.e. Customer), not by Outcome. See issue BACM11-52 and proposed resolution BACM11-58 that address the association of Customer with triggering Outcomes.
