A Federal Contractor's Runbook for Feature Flag Adoption

Before evaluating LaunchDarkly or Split on capability, confirm directly with each vendor what authorization or compliance status their platform currently holds, and whether it covers the specific environment your system operates in, GovCloud, an air-gapped network, or a standard commercial cloud. Don't assume either vendor's marketing claims about compliance apply to your specific authorization boundary; get it in writing from the vendor for your exact deployment scenario.

A flag SDK typically calls out to the vendor's service to fetch targeting rules and report flag evaluations, and for a system handling controlled unclassified information, that outbound call itself may need review. Ask each vendor for their data flow diagram and confirm what leaves your boundary, even metadata, before integrating either platform into a system that touches CUI.

Questions to put to each vendor:

• Ask each vendor for its data flow diagram showing what the SDK sends to its service.
• Confirm what leaves your authorization boundary, including flag evaluations reported back to the vendor.
• Check whether that outbound call needs review, especially for a system handling controlled unclassified information.
• Record the answers in writing so you can show them to whoever manages your ATO process.

Recovery time after a failed deployment varies widely across engineering organizations, from under an hour for the fastest-shipping teams to weeks for the slowest¹. For a contractor, that recovery time isn't just an internal metric, it's something your change-control documentation and possibly an ATO review will ask about directly. A flag-based rollback that doesn't require a new deployment is worth documenting explicitly as your fastest recovery path, separate from your standard deployment rollback procedure.

Even if a platform supports approval workflows, confirm those workflows actually satisfy your program's specific change-control requirements rather than assuming a generic feature checks the box. Walk your actual approval chain, who has to sign off on a production change and why, against what the platform can enforce, and document any gap you'll need to cover with a manual process alongside the tool.

A program that starts in a standard commercial cloud environment and later needs to move to a higher-compliance environment, GovCloud or an air-gapped network, may find that its flag platform choice doesn't travel with it, since not every deployment option is available in every environment. Ask each vendor directly about migration paths between environments before committing, especially if your program's classification or compliance requirements are expected to change over its lifecycle.

In a commercial SaaS context, shipping fast is usually the goal worth optimizing for. In a government contracting context, a slower rollout with a complete, reviewable paper trail is often the better trade, since an examiner or auditor's confidence in your process matters as much as how quickly a feature reached production. Weigh both platforms on how easily they produce that paper trail, not just on how fast they let you ship.

If a vendor can't quickly confirm their platform's compliance status for your specific environment, that delay itself is useful information about how prepared they are to work with contractors like yours. Give yourself a firm deadline for getting a written answer before committing engineering time to an integration, and have a fallback plan, a simpler homegrown flag mechanism, ready in case neither vendor's answer satisfies your program's requirements in time.

A program that waits until an ATO review is imminent to start documenting its flag change-control process will find that reconstructing months of history from memory or scattered tickets is far harder than it would have been to log contemporaneously. Start the documentation habit with your very first flag, even before a review is scheduled, since a thin but complete record from the start beats a thorough one assembled under deadline pressure later.
