Before you shortlist a supplier, get clear on the brief
A practical framework for defining requirements, comparing quotations, and planning supplier qualification.
A supplier search is easier to evaluate when everyone is working from the same requirements. Before collecting names or requesting prices, write a brief that makes your priorities explicit.
1. Define the product and the use case
Document the specification, materials, drawings, tolerances, and packaging requirements you already know. Identify which requirements are fixed and which could change. If the specification is incomplete, make the open questions visible rather than inviting suppliers to guess.
Include the intended use and destination market. Ask the appropriate specialists which testing, certification, or documentation requirements apply to your product.
2. Separate demand from aspiration
An initial order, an annual forecast, and a long-term target serve different purposes. Label them separately. Explain how firm the forecast is, how often orders might repeat, and what flexibility you need.
Discuss minimum order quantities, tooling, samples, and ramp-up capacity early. A quotation built around a large theoretical volume may not describe the economics of your first order.
3. Put the commercial assumptions beside the price
Ask suppliers to state the currency, quotation validity, payment terms, delivery basis, and included costs. Record what is excluded. Separate one-time charges from recurring unit costs.
Then compare the options using the same assumptions. Unresolved freight, duty, inspection, or tooling costs should remain visible as gaps, rather than disappearing into an apparently attractive unit price.
4. Plan the evidence you need
A shortlist is a starting point for qualification. Decide what evidence would support a purchasing decision: samples, references, production discussions, site visits, independent testing, or inspection.
The appropriate depth depends on the product and the consequences of a quality or delivery failure. Record who will review each piece of evidence and which questions must be resolved before an order.
A useful first deliverable
Aim for a brief that another person could use to explain your requirement consistently. It does not need to answer every question. It needs to distinguish what is known, what is assumed, and what must be checked next.
