From first conversation to shipped software. Five steps, no surprises.
One email, then one call. What the system needs to do, who uses it, and what it replaces.
A short written scope: what ships, what it costs, how long it takes. Fixed before any code.
Working software every week, not weekly decks. You see the real system from the first weeks.
Deployment, data migration, training. Done when it runs your operation, not when the code is merged.
Monitoring, support and changes under one running agreement. The same engineers who built it.
