Preparing an OEM or ODM development brief

Separate an existing-model change from a new design

Start with the closest existing product and describe what needs to change. A logo or label request is different from a new housing, optical arrangement or controller interface. Mark each requirement on a drawing or sample reference so the supplier can identify the engineering work, tooling questions and documentation needed.

For a brand-specific version, provide approved artwork, placement, colour references and packaging requirements. For functional changes, describe the intended use, electrical supply, mounting constraints and interfaces. Avoid relying on a reference photograph to communicate details that are hidden inside the assembly.

Agree the approval stages

Request a written proposal that separates the standard configuration from the requested changes. Identify which dimensions, materials, components or functions need confirmation. Where drawings or samples are part of the process, agree who reviews them and which revision becomes the production reference.

Ask how proposed changes affect the available test evidence and product documentation. Evidence for a standard configuration should not automatically be treated as covering a modified design. If the project requires additional review or testing, identify that work and its responsibility before the production order is finalised.

Keep future orders consistent

The accepted drawing, bill of materials, artwork and packing requirements should have clear identifiers. Use those identifiers in repeat orders and spare-parts enquiries. Record agreed substitutions or revisions so that the receiving team can distinguish an approved change from an unintended difference.

Send GAOQIAO the project specification, expected quantity and delivery destination together with the customization brief. This supports a discussion of feasibility, sample arrangements, production planning and support. Any lead time or commercial commitment should be confirmed for the actual project rather than assumed from a general OEM or ODM statement.
