Role-Based Access & Approval Rules for Feature Flags

Setting role-based access and approval rules for feature flags lets you control who can create, modify, and release features in your application, and it adds a safety gate so changes are reviewed before they go live. This guide walks you through configuring permissions and approval workflows in a typical feature flag management platform. You’ll need administrator access to your feature flag service and a clear idea of your team’s roles and release process.

What You’ll Need

• Administrator or owner access to your feature flag management platform (e.g., LaunchDarkly, Split, Flagsmith, or an in-house system).
• A list of team members and the roles you want to assign (e.g., Developer, QA, Product Manager, Admin).
• Knowledge of your release process: who should approve changes and how many approvals are required.
• Access to your project’s environment settings (e.g., development, staging, production).

Step-by-Step

1. Define your roles and permissions. Decide which actions each role can perform: create flags, edit flag configurations, toggle flags on/off, archive flags, or manage approvals. Common roles include:
   • Admin – full access, including managing roles and approval rules.
   • Developer – create and edit flags, but may require approval for production changes.
   • QA/Test – view flags and toggle in test environments only.
   • Product Manager – view flags and maybe create, but not toggle in production.
2. Open your feature flag platform’s settings. Navigate to the “Roles” or “Permissions” section in your dashboard. This is typically under “Access” or “Team” settings.
3. Create custom roles (if supported). If your platform allows custom roles, create roles that match your team’s needs. Assign specific permissions to each role, such as “Can create flags,” “Can edit targeting,” “Can toggle in production,” and “Can approve changes.”
4. Assign roles to team members. Go to the “Members” or “Team” tab, invite or select existing members, and assign them the appropriate role. Make sure each person has the least privilege necessary to do their job.
5. Set environment-specific permissions. Most platforms let you restrict actions per environment. For example, you might allow developers to toggle flags in staging but require approval for production. Configure these settings in the environment’s permissions or in the role’s environment scope.
6. Enable approval rules. Look for “Approval Rules” or “Change Requests” in your settings. Enable the feature and define the conditions that trigger an approval, such as:
   • Any change to a flag in production.
   • Turning on a flag that has been off for more than 30 days.
   • Changes to targeting rules that affect more than 10% of users.
7. Configure the approval workflow. Specify who can approve changes (e.g., a specific role like “Admin” or “Release Manager”) and how many approvals are required (e.g., 1 or 2). Some platforms allow you to set different rules for different environments.
8. Test the setup. Create a test flag and try to make a change that requires approval. Verify that the change is blocked and that an approval request is sent to the designated approvers. Approve it and confirm the change goes through.
9. Document your process. Write a short internal guide explaining how to request approval and what the review criteria are. This helps team members understand the workflow and avoids confusion.
10. Review and adjust regularly. As your team grows or your release process changes, revisit the roles and approval rules to ensure they still fit. Remove or adjust permissions for people who change roles.

Common Mistakes

• Giving everyone admin access. This defeats the purpose of role-based access. Always use the principle of least privilege.
• Not setting environment-specific rules. If you require approval for all changes, including development, you’ll slow down your team. Usually, you only need approval for production or high-risk flags.
• Too many approvers. Requiring multiple approvals for every change can cause delays. Limit multi-approval rules to high-impact changes.
• Forgetting to test the approval flow. If you don’t test, you might discover that approvals don’t work correctly during a critical release.
• Not documenting roles. If team members don’t know what they can do, they may get stuck or try to bypass the system.

Tips

• Start with a simple setup. Use built-in roles if they fit, then customize as needed. You can always add complexity later.
• Use teams or groups. If your platform supports user groups, assign roles to groups instead of individuals. This makes it easier to manage when people join or leave.
• Make approval rules specific. Instead of “all production changes,” consider “changes that affect more than 5% of users” or “turning on a flag that has been off for more than 2 weeks.”
• Leverage audit logs. Enable audit logging to track who made changes and who approved them. This is invaluable for troubleshooting and compliance.
• Integrate with your CI/CD pipeline. Many platforms offer APIs or webhooks that can enforce approval rules programmatically, ensuring changes are reviewed even when made via automation.

Troubleshooting

• Changes are not being blocked. Check that approval rules are enabled for the correct environment. Also, verify that the user making the change does not have a role that bypasses approvals (e.g., Admin).
• Approval requests are not reaching the approver. Check the notification settings in your platform. Ensure the approver has an email address or Slack integration configured. Also, verify that the approver is assigned the correct role.
• Cannot create a custom role. Some platforms only allow custom roles on higher-tier plans. Check your subscription or contact support.
• Users can still toggle flags in production despite restrictions. Double-check the environment permissions. In some platforms, you need to set permissions both at the role level and the environment level.
• Approval workflow is too slow. Reduce the number of required approvals, or set a time limit for approvals (if supported). Alternatively, allow auto-approval for low-risk changes.

Frequently Asked Questions

1. Can I set different approval rules for different environments? Yes, most platforms allow you to configure approval rules per environment. For example, you can require approval for production changes but not for development.
2. What happens if a change is rejected? The change is not applied, and the requester is notified. They can modify the change and resubmit it for approval.
3. Can I require multiple approvals for a single change? Yes, many platforms let you specify the number of approvals needed. This is useful for high-risk changes.
4. Do approval rules apply to API changes? If your platform supports API-based changes, approval rules can often be enforced via webhooks or API checks. However, this may require additional configuration.
5. How do I know who approved a change? Check the audit log or change history for the flag. It should show the approver’s name and timestamp.
6. Can I bypass approval rules in an emergency? Some platforms allow admins to override approval rules, but this should be used sparingly and logged. Check your platform’s documentation for emergency procedures.
