Handoff That Holds: Specs Built for B2E Edge Cases
A clean handoff is what keeps a B2E program on schedule, so I treat delivery as a deliverable in its own right — not a zip of screens thrown over the wall. For a PMO, the risk isn't the happy path; it's the questions developers hit on day three that send a ticket back to design and quietly burn a sprint.
So I specify the states most consumer handoffs skip. Every field flow ships with its offline, syncing, error and conflict states defined. Camera, GPS and QR interactions come with permission-denied and failure paths. I document how each screen behaves against the legacy integration — what's read-only, what validates server-side, what a late sync looks like to the user.
I deliver against the Design System so engineers reuse components instead of rebuilding them, and I include i18n and accessibility (WCAG) notes inline rather than as a later 'phase two' surprise. The result is a spec a developer can build from without guessing, and a backlog where edge cases are scoped, not discovered. That's the difference between a handoff that holds the timeline and one that erodes it ticket by ticket.
