A strong factory brief does not try to predict every answer. It makes the product intent, the non-negotiables, and the unknowns clear enough that a supplier can respond with a useful quote, the right questions, and an honest view of manufacturability.
Give a partner enough context to cost the right product. Then make it obvious which questions need a decision before a quote becomes a commitment.
Start with the product story
Describe the person, use case, and desired outcome before listing engineering detail. This helps a manufacturer understand the customer experience they are protecting when they suggest an alternative material, process, or tolerance.
- Who uses the product, in what situation, and what problem does it solve?
- What must feel, look, or work in a particular way?
- What matters most if trade-offs appear: cost, durability, lead time, finish, sustainability, or serviceability?
Include the manufacturing essentials
A supplier needs enough detail to determine process, tooling, materials, labour, capacity, quality expectations, and risk. Put the current version of these inputs in one controlled package.
Product and parts
Provide assembly drawings, part drawings, CAD, BOM, dimensions, materials, finishes, colour references, and any critical tolerances.
Commercial scope
State the expected annual volume, first-run quantity, target unit cost if appropriate, tooling expectations, sample requirements, and desired timing.
Quality and compliance
Write the acceptance criteria, test methods, visual standards, required certifications, packaging requirements, and evidence you expect before release.
Open questions
Name the decisions you have not made. A factory can help solve them—but only if it knows they are open, rather than accidental omissions.
Be specific about what is controlled
Not every file has the same status. Label what is approved for quotation, what is a reference only, and what must not be used for production. Record the version date and owner for every core document.
- Give the RFQ a unique reference and a response deadline.
- State which release the supplier is quoting and how they will receive updates.
- Ask suppliers to call out assumptions and proposed substitutions explicitly.
Ask for a useful quote—not just a price
A meaningful quote lets the team compare partners without reverse-engineering a spreadsheet. Ask for unit cost, tooling, MOQ, lead time, capacity, payment terms, packaging assumptions, quality plan, and conditions that could change pricing.
Connect approved product inputs, supplier questions, quote comparisons, and selection decisions in a workspace the whole team can follow.
