Context
A mining implementation needed a live release under commercial pressure after earlier delivery drift.
Release path
The live release was narrowed into gated movement.
Contract, build, migration, live support, and hypercare were held together by clear release gates.
Approach
Heztasy rebuilt the plan around release gates, migration checks, role-based readiness, and hypercare ownership.
Outcome
The D365 release went live in 11 weeks from signed contract, with no severity-1 incidents during the stabilization window.
