Coating Trials with Several Outcomes: Name the Primary Decision
Testing many outcomes creates opportunities to select whichever result looks best. A primary decision criterion keeps the evaluation focused.
Updated · NANOLAB Knowledge
Practical approach
Define the main endpoint before testing and report secondary observations with their role and limitations.
A candidate that misses the agreed cleaning objective should not be declared the overall winner solely because an unrelated gloss value is higher.
Decision limits
Do not change the purchasing question after seeing the results without making that change explicit.
