Compare the proposed product and site together
Start with a defined product brief, not a company-wide certificate or a unit price alone. Give each prospective supplier the same composition, strength, dosage form, release type, market, quantity and packaging requirements. Ask which site and manufacturing stream would handle that exact project.
Use a comparison sheet that makes gaps visible
| Decision | Evidence to request | Question to resolve |
|---|---|---|
| Product and site fit | Proposed facility, current licence and applicable product scope | Does the evidence cover this composition, form and market? |
| Quality readiness | Document list, current specifications, methods and relevant validation information | What exists, what can be reviewed, and what work remains? |
| Pack readiness | Primary pack specification, printed components and stability requirements | Which pack is included in the quote and what changes need assessment? |
| Commercial scope | Batch and pack quantities, one-time costs, exclusions and payment milestones | Are quotes based on the same units and responsibilities? |
| Delivery readiness | Material, artwork, production, testing and release dependencies | What starts the lead-time clock and who controls each dependency? |
| Lifecycle support | Agreed change, complaint, recall and reorder responsibilities | How will issues and changes be communicated after dispatch? |
Use Walter's published evidence to plan the review
Explore the facility pages, certification library and plant walkthrough to prepare specific questions. Photos identify their location or representative status; equipment and dosage-form scope vary between sites. Ask for the document scope and current validity relevant to your proposed engagement before making a supplier decision.

Separate an open question from a confirmed commitment
Record each item as confirmed with evidence, awaiting clarification, or not applicable. Include the document revision and the person responsible for the next answer in your own review record. A proposed MOQ, dispatch date or shelf life should remain a proposal until the relevant technical and commercial work supports it.
Prepare a focused plant visit
- Name the dosage form, proposed product and supplier-review objectives.
- Agree the relevant site, participants and areas available for the visit.
- List the documents and processes you want to discuss in advance.
- Agree confidentiality and permitted access before sharing controlled information.
- Record follow-up questions, owners and the evidence needed to close each item.
