A new supplier document differs from the version your team reviewed and the effect needs assessment before acceptance.

The useful bits

  • Both specification versions
  • Specific changed fields
  • The response should identify the actual differences and the options still available for authorized review.

Before you write

Use this example when a new supplier document differs from the version your team reviewed and the effect needs assessment before acceptance. Gather the details below so the recipient can act without asking you to reconstruct the situation.

  • Both specification versions
  • Specific changed fields
  • Technical and commercial review owners

An email you can adapt

The subject “Specification change check for [item]” identifies the request. Replace each bracketed field with a checked detail and remove any sentence that does not describe your situation.

EXAMPLE / ADAPT TO YOUR SITUATION
Subject: Specification change check for [item]

Hi [name],
Specification [new version] differs from [previous version] in [fields]. Please explain the change, its reason and any effect on compatibility, operation or the agreed scope. We have not accepted the revision by receiving the document. [Technical owner] and [commercial owner] will review the implications through the normal process. If the earlier version remains available, please confirm that separately so we can assess the supported options.
Best, [sender]

Check the boundary

Do not assume a specification change is harmless just because the overall product name is unchanged.

What a useful reply should settle

The response should identify the actual differences and the options still available for authorized review.

Record the approved version explicitly before procurement or technical work uses the revised specification.
