You can edit a decision model at any time when it's in the Draft or Configured state. However, a decision model in the Active state is view-only. To edit an active decision model, you must either deactivate or version it.

1. In your project, click Decision in the left toolbar to view the list of decision models.
2. In the Decisions box, point to the decision model you want to edit or view, click , and click Edit or View.
   The decision designer opens in the edit or view mode, based on what you chose.
