Identify the authoritative description
A material name may appear in a drawing, a spreadsheet, a supplier quotation, and an email. Decide where the approved description lives and how other documents refer to it. Record the grade or product identifier at the level actually agreed, along with the form, condition, and finish that affect the application.
Avoid relying on a prototype's color or appearance to communicate a production requirement. A similar-looking sample may have a different underlying material or surface treatment. The handover should say which characteristics are intentional and which were merely convenient for the prototype.
Transfer the reasoning as well as the selection
Record why a candidate was retained, which requirements it addresses, what evidence supports the decision, and what still needs verification. A future maintainer should be able to distinguish a deliberate choice from an assumption that happened to remain in a drawing.
Include rejected alternatives only when their rationale is useful for a future change. The handover is not an archive of every conversation. It should provide enough context to stop a later substitution from unknowingly reintroducing a problem that the original decision had considered.
Define how a change is reviewed
A supplier change, a different finish, or a revised manufacturing process can affect more than a material label. Identify who reviews a proposed substitution, which interfaces it may affect, and what evidence is needed before acceptance.
Keep revisions traceable across the brief, comparison, observation record, and final description. When historical documents are retained, mark their status clearly. A superseded sample should not remain the unqualified visual reference for the current design.
Make the package usable by its recipient
A design-transfer scope can organize the requirement references, candidate rationale, source documents, open actions, and ownership into a compact package. Use stable file names and a revision index rather than scattering the latest information across unrelated messages.
Review the package with the intended recipient. Ask them to locate the material description, explain a surface requirement, and identify who can approve a substitution. Any manufacturing, procurement, certification, or ongoing maintenance responsibility needs to be agreed separately rather than inferred from the existence of the documents.
