integration-slice-orchestration

Frontend and backend integration is coordinated by delivering features in small, vertical slices that rely on frozen contracts, reducing integration risk and rework. Each slice touches both FE and BE, generating per-slice verification signals and recorded HANDOFF transitions.

A vertical slice in FE-BE integration is a minimal, incremental feature unit that touches both frontend and backend, relies on frozen contract surfaces, and produces a standalone verification signal to track progress and risk.

Handoffs during parallel FE and BE development are managed by recording HANDOFF transitions for each integration slice, tracking ownership and verifying that contract surfaces remain frozen before passing responsibilities between teams.

Incremental slicing for feature integration should be used when a feature touches both frontend and backend, contracts are frozen, and parallel FE/BE work is planned to minimize integration risk and ensure per-slice verification.

To define the first integration slice, outline the frozen contract surface, specify backend and frontend responsibilities, and define the verification signal, then record the transition as a HANDOFF to track progress and ownership.
