Validation & Reliability — question 10 of 10

Write a real answer. It is graded against the question's rubric, and the mastery movement is computed by the same engine the product uses. Scoring here is deterministic rather than model-written, so this page costs nothing to run and nothing is saved. In a track built from your own posting, the same rubric is graded by the model, which is what produces feedback about your reasoning rather than about coverage.

A board passed every validation test on the bench, in the thermal chamber, and in vibration -- no issues at all. Six months after shipping, about 2% of units in the field start failing, but only in humid coastal regions; units in dry climates show no failures. Walk me through how you'd approach root-causing this, and what you think validation missed.

How sure are you?

Being confidently wrong costs more mastery than admitting a guess — that is deliberate, and it is how misconceptions get found.

Neither is graded, and nothing here is recorded.
