Trial Success Criteria: Define Success Before Testing
A trial is only meaningful if success was defined before it ran. This guide lists the criteria a client trial can be judged against, and makes the central point: a product can freeze dry successfully and still be commercially unattractive. Trials separate the two.
Category: Client Trials
The trial principle
A product can freeze dry successfully but still be commercially unattractive. Technical success is about dryness, texture and stability. Commercial success also asks: does the yield make sense, does the cycle cost too much, does the package sell, does the margin work? Trials separate the two questions, and both must be asked.
The Success Criteria
Agree with the client (or with yourself) which criteria matter, and what 'pass' means for each, before the batch runs:
- Crisp snack. For snack products: does the finished piece have the intended snap and mouthfeel, and does it stay crisp after packaging and storage?
- Good rehydration. For rehydrating products: does the product take water back up in a useful time with an acceptable texture?
- Stable powder. For powders: does the dried product mill or grind cleanly, flow freely, and stay free-flowing in storage?
- Target yield. Does the measured dry yield fall in the range the economics require? The exact number comes from the trial itself, not from an assumption.
- Acceptable cycle. Was the cycle time workable for the operation's schedule and pricing?
- Good packaging. Does the finished product package well: no clumping, correct absorbers, stable seal, honest label?
- Acceptable cost. Does the cost per finished weight or per package leave room for the business's margin at a sellable price?
Technical Success vs Commercial Attractiveness
The crispest snack in the world is not a business if it yields almost nothing per tray, if the cycle runs far too long, or if the cost per package exceeds what anyone will pay. Conversely, a technically imperfect result can sometimes be fixed by preparation changes. The trial report should answer both halves: did it freeze dry well, and does the math make sense? The client trial guide and the test report guide carry both halves through.
Define the pass before the run
Writing the criteria down before the batch prevents the most common trial failure: judging success by how the results feel afterward. A trial without pre-agreed criteria is a batch, not a test. See Lab methodology for how the Lab structures the same discipline.
From trial to production decision
- Technical pass but economic fail: document honestly, tell the client what would have to change, and do not push production.
- Technical fail with a fix path: propose a modified preparation and consider a second trial.
- Both pass: build the production quote from the measured trial data, per the quoting guide.
Frequently Asked Questions
What if the client only cares about texture?
Then agreed success is texture, but the report should still carry yield, cycle and cost, because the client will care about them the moment production pricing appears.
Can a trial pass technically and still not proceed?
Yes, and that is a useful result, not a failure. A product can freeze dry beautifully and still be commercially unattractive at the measured yield, cycle and cost.
Who defines the criteria?
The operation and the client together, before the run. The operation brings the process knowledge; the client brings the market knowledge. Both are needed for honest criteria.
Key Takeaways
- Write success criteria before the batch: texture, rehydration, powder stability, yield, cycle, packaging and cost.
- Technical success and commercial attractiveness are separate questions; trials answer both.
- A product can freeze dry successfully yet still not make commercial sense, and the trial should say so.
