Enterprise Engineering, one level up.

We map the system as it actually runs, not as the docs say it does.

Scope, sequencing, and the rollback plan — written before the build plan.

Interfaces and architecture reviewed together, not handed off in sequence.

Shipped in increments a client can see and react to every two weeks.

Load, security, and failure-mode testing — rehearsed, not just documented.

Shadowed traffic, staged cutover, and a rollback that's actually been run.

On-call alongside your team until the system is boring again.
