Agree the handover before development starts

List the design files, firmware or software source, manufacturing information and documentation needed for the next stage. File formats and tool versions should be agreed where they affect reuse.

Record how to build the software, configure the hardware and run the agreed checks. Include the relevant versions and the known operating conditions.

A useful handover distinguishes completed requirements, accepted limitations and unresolved issues. Each remaining item should have an agreed next action.

Tie each review or payment milestone to specific deliverables and acceptance evidence. Update the scope explicitly when requirements change.

Clarify the source files to be handed over, permitted reuse and any third-party licenses or tools needed to maintain the product. Capture the agreed terms in the project documents.
