Specifying the Voting Outcome

You can specify a voted-upon outcome that overrides the default outcome selected in the Default Outcome list. This outcome takes effect if the required percentage is reached. Outcomes are evaluated in the order listed in the table.

To specify group voting details:

  1. Go to the Vote Outcome section of the Edit Participant Type dialog box for the parallel type.
  2. From the list in the Voted Outcomes column, select an outcome for the task (for example, Any, ACCEPT, REJECT, or any other outcome specified in How to Specify a Task Outcome).

    The Any outcome enables you to determine the outcome dynamically at runtime. For example, if you select Any and set the outcome percentage to 60, then at runtime, whichever outcome reaches 60% becomes the final voted outcome. If 60% of assignees vote to reject the outcome, then it is rejected.

  3. From the list in the Outcome Type column, select a method for determining the outcome of the final task.

    • By Expression: Dynamically specify the details with an XPath expression.

    • By Percentage: Specify a percentage value that determines when the outcome of this task takes effect.

  4. From the list in the Value column, specify a value based on your selection in Step 3.

    • If you selected By Expression, click the Browse icon to the right of the field to display the Expression Builder dialog box for creating an expression.

    • If you selected By Percentage, enter a percentage value required for the outcome of this task to take effect (for example, a majority vote (51) or a unanimous vote (100)). For example, assume there are two possible outcomes (ACCEPT and REJECT) and five subtasks. If two subtasks are accepted and three are rejected, and the required acceptance percentage is 50%, the outcome of the task is rejected. Figure 29-34 provides details.

      This functionality is nondeterministic. For example, selecting a percentage of 30% when there are two subtasks does not make sense.

  5. Click the Add icon to specify additional outcomes.
  6. In the Default Outcome list, select the default outcome or enter an XPath expression for this task to take effect if the consensus percentage value is not satisfied. This happens if there is a tie or if all participants do not respond before the task expires. Seeded and custom outcomes that you entered in the Outcomes dialog box in How to Specify a Task Outcome display in this list.
