Discussion Framework
Thi i l iThis is a class exercisePick up from the Tuesday topic:“Product/Family Best Foot Forward (BFF) TestProduct/Family, Best Foot Forward (BFF), Test Points and Qualification Ranges”Start with test point(s) from just completed SUT testingRun through the Energy Star qualification rules to identify product family / range / SKUsidentify product family / range / SKUs
