outcome is the second optional parameter in the complete method. tasks bind the outcome to an outgoing transition. if no outcome is given, then the task should only have 1 outgoing transition. if a task has multiple outgoing transition, the outcome must be specified and match the transition name. providing no value for outcome (or null) works if there is a single outgoing transition or if there is a transition without a name. does this answer the question?
