Connect the change to the production handover

Follow the engineering review, rework requirements and inspection handover for a returned-board ECN.

Use the case to structure the discussion: clarify the engineering requirement, identify the affected stock or batch, prepare materials and work instructions, then agree inspection and release records.

Requirements and approvals must be confirmed for each project before production or rework begins.
