Create decision models to make your business processes less complex, easier to manage, and more robust in the face of change.
- On the Composer Home page, click Create and select New Decision Model.
- Enter information into the Create Decision Model dialog box. Here are a few things to note:
Field Description Name and Description
Make sure the decision model name and description are useful. Give the user a good idea of what the decision model is all about and why they might want to use it. Good names and descriptions help users distinguish decision models with a similar title or purpose. Also, you can’t change the name after the decision model is created.
Select the space where the new decision model will be stored. To create a new space, select New Space from the drop-down list.
Most of the time you’ll want to leave the Open Immediately check box selected so you can start configuring and testing your decision model right away.
Deselecting the check box is good if you want to create placeholders for several decision models at once and modify them at a later time.
- Click Create.
The decision model editor enables you to:

If you add a new service or change the service definition within your decision model, you’ll need to create a new reference to the decision model on Process, re-implement the activity, and re-associate the data.
Within the selected decision model, click Options of the decision, service, input data, or input type to edit it.
To delete a decision model, click Options and then select Delete Model.

Deleting a decision model that is currently in use in one or more applications deactivates and deletes all the deployed decision model snapshots.

Deleting a decision model or its snapshot that is currently in use in one or more applications does not delete references to it in the Process application. This may result in errors during runtime when the application tries to call the decision service associated with a decision model that has previously been deleted from the DMN server.
