Mobile Feature Expansion Sprint. @mobile-feature-sprint

Your mobile app is live and users want the next thing — payments, chat, a new module, a redesigned flow. But your team is elsewhere, or the original builders are gone, and adding to a production app is not greenfield work: one careless dependency bump can break what works. The Mobile Feature Expansion Sprint adds one clearly bounded feature set to your existing app, with the respect a live codebase demands.

The finish state is the feature in your users' hands: built inside your existing codebase and conventions, regression-tested against what already worked, and released through the stores.

Feature Scoping

The feature set bounded precisely, plus a codebase orientation: architecture, conventions, test coverage, and the risk map of what the change could touch.

Production Build

The feature built within your existing patterns and stack — native or cross-platform — matching the codebase rather than importing a second style.

Regression Safety

Tests around the new feature and the paths it touches, plus a regression pass on core journeys before any release candidate ships.

Store Release

The release managed through both stores as needed — staged rollout, monitoring on the new feature, and a rollback plan that was written before it was needed.

1. Scope — Bound the feature set, orient in the codebase, and agree the regression surface and release plan.
2. Build — Build in sprints with test builds in your hands, new tests landing alongside the feature.
3. Handover — Staged store release, monitoring on the new paths, and code handover in your repository as always.

The Mobile Feature Expansion Sprint 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.

We did not build the original app. Is that a problem?

It is the usual case. The orientation phase maps the codebase before commitments are made — and if the audit finds the foundation too fragile to extend safely, we say so and scope the stabilisation first.

What counts as one bounded feature set?

A scope one team can ship in one release cycle: a payment flow, a chat module, a reporting screen. If your list is bigger, it becomes multiple sprint items on your plan — sequenced, not crammed.

What if the app also has stability problems?

Feature work on an unstable app compounds the instability. The Mobile Crash & Stability Sprint is the sibling item for that — often scheduled first, so the expansion lands on solid ground.
