Feature Flag Platform Implementation — @feature-flag-platform

Teams without feature flags ship by coupling two decisions that should be separate: when code deploys and when users see it. The result is release trains, long-lived branches, and rollbacks as the only undo. The Feature Flag Platform Implementation introduces the decoupling properly — a flag platform integrated into your services and frontends, progressive rollout by percentage or audience, and kill switches that turn a bad release into a config change instead of an incident.

Governance ships with it, because unmanaged flags become their own debt: naming and ownership conventions, lifecycle rules that retire stale flags, and audit trails on changes. The finish state is the platform in production use — real features released through percentage rollouts by teams trained on the workflow, with the first kill switch tested rather than trusted.

Flag Platform & SDK Integration

Platform setup — LaunchDarkly, Unleash, Flagsmith, or your selected option — with SDK integration across the in-scope services and frontends, evaluated at latency your paths can afford.

Targeting & Progressive Rollout

Percentage rollouts, audience targeting by attribute or segment, and environment-aware defaults — the mechanics of releasing to 1%, then 10%, then everyone.

Kill Switches & Safety

Kill-switch patterns for risky paths, fallback behavior when the flag service is unreachable, and integration with monitoring so a rollout can halt on error signals.

Flag Governance & Lifecycle

Naming, ownership, and expiry conventions enforced in tooling, cleanup workflow for retired flags, and audit history on every change.

1. Scope — Fix the platform choice, in-scope services, and governance rules; pick the first features to release through flags.
2. Build — Integrate SDKs, wire targeting and kill switches, and run the first progressive rollouts with the owning teams.
3. Handover — Team training on the release workflow, governance documentation, and the flag lifecycle process in operation.

The Feature Flag Platform Implementation is a menu item on the Scrums.com delivery catalog, available at every plan tier. Add it to your plan backlog and your delivery team schedules it like any other item — scoped, tracked, and reported through the SEOP. See Delivery Plan Tiers.

Buy a flag service or self-host?

Hosted platforms win on speed and edge evaluation; self-hosted options win on data residency and cost at scale. Scoping compares against your constraints — the integration work is similar either way.

Does this include A/B testing?

Experimentation hooks are built in — exposure events flowing to your analytics — so experiments can run on the same flags. Full experiment design and statistics tooling is a follow-on, added once flag discipline exists.

How do we avoid flag sprawl?

Lifecycle governance is half the deliverable: flags carry owners and expiry from creation, and the cleanup workflow retires them as releases complete. Sprawl is what happens when flags are adopted without this half.
