Validate one performance claim end to end
Marketing wants to claim that a new jacket is waterproof, breathable and durably water repellent. You have the fabric report, a first sample and four weeks.
Who this is for: Technical developers, quality and laboratory staff, product managers.
What you produce: A validation file: the claim wording, the test plan with criteria, the construction evidence, the care instruction, and the claim you refuse.
The writing space below is your private draft: it is saved on this device, and to your account when you sign in, and nobody marks it. When your draft is ready, you can submit it in the trainer review section above for written feedback. Review is optional: your certificate depends only on the graded quizzes and the final assessment.
Task 1
Write the claim wording you can defend, and the wording you reject, with the reason for each.
What a good answer contains: A good answer states conditions and limits in the claim itself and rejects unbounded words that no test supports.

Task 2
Write the test plan: methods, sample points, sample sizes, acceptance rules and the action on failure — decided before testing.
What a good answer contains: A good answer sets acceptance rules in advance and includes garment-level as well as fabric-level evidence.

Task 3
State the construction evidence needed: seams, taping, closures and the trial that proves the settings hold.
What a good answer contains: A good answer requires a seam performance trial with recorded settings and a peel or water-entry check, not a visual inspection.

Task 4
Write the care instruction and the durability position, including how repellency is restored.
What a good answer contains: A good answer reflects tested wash conditions and explains restoration honestly, rather than copying a label from another product.
