Factory Acceptance Test Skill

A FAT is the last moment a defect is the factory's problem instead of yours. This skill writes the plan (or the report) with the parts that actually get argued over at the line: which spec clause each test covers, how many units get pulled and at what AQL, what exactly fails a lot, and who signs — so acceptance is a decision with a name on it, not a vibe at the end of a factory visit.

What This Skill Produces

• A test coverage matrix mapping every test to the spec requirement it verifies
• A sampling plan (ANSI/ASQ Z1.4) with lot size, inspection level, and AQL per defect class
• Unambiguous pass/fail criteria and lot accept/reject rules
• Golden-sample handling procedure
• A deviation log format and a sign-off block with authority levels

Required Inputs
