Make the RFQ comparable
Send the same drawing revision, material, finish and inspection requirements to each supplier. Separate sample, first-order and expected repeat quantities; ask for tooling, gauges and other one-time items to be identified.
QUOTE SCOPE • SECOND SOURCE • REPEAT ORDERS
Compare the same part. On the same terms.
Compare quotations against the same drawing revisions, quantities and acceptance records. Use real component references and anonymous order milestones to prepare a part-by-part RFQ, including the checks, packing and change controls needed for the next release.

ONE CONTROLLED REQUIREMENT
Compare the scope.
Then compare the quotation.
Compare suppliers using the same drawing revision, material, quantities and acceptance criteria. For a multi-part order, align the requirements by line before discussing a combined schedule.
YOUR PROJECT. YOUR PRIORITIES.
Make the purchasing
decision specific.
Align engineering, sourcing and quality around a clear part definition before the quotation and sample review.
Define supplier qualification around the part
Agree the evidence required for sample approval, including critical dimensions, material documentation and any assembly evaluation. If specific certifications or traceability are mandatory, verify the applicable scope before placing the order.
Control what changes after approval
Keep a record of the approved sample, revision, packing and acceptance conditions. Require review of changes to the drawing, material, finishing route or inspection scope before the next order is released.
YOUR NEXT ORDER / EVIDENCE & REQUIREMENTS
Compare the part, the records and the handover.
A comparable quotation needs a shared part definition. These anonymized records show order scope and delivery milestones to discuss alongside your own acceptance requirements.

How should a second-source comparison start?
Use the same controlled specification and acceptance criteria for both sources. Document deviations, exclusions and one-time costs explicitly before comparing the total quotation.
Product examples help define the conversation. Suitability is assessed against your component specification.
