What a good handover actually contains

Clients rarely ask us about handover during a pitch, and it is the part they remember a year later. A codebase you cannot change confidently is a liability regardless of how well it runs today.

The four things we hand over

• A test suite that fails for the right reasons. Coverage of business rules and endpoints, not of getters. If breaking a rule does not turn the suite red, the suite is decoration.
• A one-command local setup. Clone, install, seed, run. If the first day of a new developer is spent reconstructing an environment from memory, the environment is undocumented.
• Seeded data that resembles production. Real content shapes, real edge cases, deterministic values. Empty databases hide bugs that only appear once a table has rows.
• A written record of the decisions. Not an architecture diagram nobody updates — a short note per non-obvious choice explaining what was rejected and why.

Run the handover before it is due

We ask the receiving team to make a small change while we are still engaged, and we watch without helping. Everything that slows them down is a gap in the handover, and it is far cheaper to close it then than by email three months later.
