The instance can automatically assign a task to a user or group based on pre-defined
conditions by using data lookup rules and assignment rules.
* **[Assignment rules module](https://www.servicenow.com/docs/ctjCc3QXGGV1f06tphfykg)**   
  The Assignment rules module allows you to automatically set a value in the assigned_to and assignment_group fields when a set of conditions occurs.
* **[Data lookup rules](https://www.servicenow.com/docs/ImQKbx_X_0oFdRD7E1G1mg)**   
  Data lookup rules offer a generic way to change any field value, not just assignment fields.
* **[Precedence between data lookup, assignment, and business rules](https://www.servicenow.com/docs/Z~toLWpXY8d4b5ChlF5pYA)**   
  Scripts, assignment rules, business rules, workflows, escalations, and engines all take effect in relation to a database operation, such as insert or update. In many cases, the order of these events is important.
* **[Workflow assignments](https://www.servicenow.com/docs/0tgvH2rxefz5FFGncxEOwg)**   
  An alternative to creating data lookup or assignment rules is to create one or more workflow tasks that assign a task record as part of a workflow.
* **[Baseline assignment rules example](https://www.servicenow.com/docs/cr7uOKkF73owaDkra9Sm0A)**   
  A baseline instance contains certain assignment rules.
* **[Create an assignment rule](https://www.servicenow.com/docs/4KfuYYmdSpaumk2T2tKlZQ)**   
  Automatically assign a record according to one or more conditions in an assignment rule. Assignment rules are designed to run at the time you open a record.
* **[Create an assignment data lookup rule](https://www.servicenow.com/docs/mf5Nz~Mjt2OYrELTd~P1IA)**   
  Automatically assign a record using Data Lookup and Record Matching.
