This provides an additional layer of control and security for sensitive operations in your organization. ## Overview Workflow approvals in Serval offer flexible options to match your organization's approval processes: * **Individual Approvers**: Specify one or more users who can approve the workflow. * **Group-based Approvals**: Leverage groups created in Serval or synced from external systems. Multiple groups can be added to a single approval step. * **Manager Approvals**: Automatically route approvals to the requester's manager. * **Multi-step Approvals**: Create approval chains where multiple parties must approve in sequence. * **Self-Approval**: Toggling self-approval enables users, who are also approvers for the workflow, to approve their own requests. Workflow Approvers Block ## Configuring Workflow Approvers To configure approvers for a workflow, click **Add Approvers** above the workflow blocks. This will open the workflow approvers configuration dialog. Workflow Approvers Dialog ### Adding Approvers In the configuration dialog, you can: 1. **Select Users or Groups**: Use the toggle to switch between individual users and groups 2. **Search for Approvers**: Type a name or email to find specific users or groups 3. **Add Special Members**: Select "User's manager" to automatically route to the requester's manager 4. **Configure Self-Approval**: Toggle whether approvers can approve their own requests ### Multi-step Approval Process For workflows requiring multiple levels of approval, you can add additional approval steps by clicking "Add approval step". This allows you to create approval chains such as: 1. First, the requester's manager must approve 2. Then, a member of the Engineering team must provide approval 3. Finally, a specific member of the IT team must provide final approval Configured Workflow Approvers ## Best Practices * **Use Groups for Scalability**: Instead of adding individual users, consider using groups to make approval management easier as your team grows * **Leverage Manager Approvals**: For requests that need hierarchical approval, use the "User's manager" option * **Consider Self-Approval Settings**: Carefully evaluate whether approvers should be able to approve their own requests based on your security requirements * **Document Approval Chains**: For complex multi-step approvals, document the approval flow for your team's reference * **Sole Approver**: In the case of a specified user to be the sole approver, it is recommended that you turn on self-approval. Otherwise, the workflow will be unable completed whenever the requester is also the sole approver.
