Other Performance Examples Other registration performance examples (Figure 3) provide a recap of the system now in use at the world's most modern Lean and green PCB fabricator, GreenSource Fabri- cation. e registration and perfor- mance soware being used at Green- Source provides hindsight from pro- duction data, insight as to what's hap- pening in real-time, and foresight into improving the performance of WIP through prescriptive actions. Parametric PCB Coupons ere are parametric coupons that can be placed on test panels or pro- duction panels that will provide data Figure 2: Registration software collects and analyzes various measurement data to improve the performance of each production panel 2 .
