Adaptive Test Building Blocks ITRS TWG Data Various sources may be real time, historical or feed-forward, & structured to feed decision engine (algorithms) Data Structure & Control Path Deliver targeted data to the analysis engine & decisions to the action point Decision Algorithms Models to automatically adjust test based on input data Analysis Engine(s) Executes rules/algorithms on the data based on product parameters. May be separate or embedded in test program or station controller software Station Controller To communicate with or run the analysis engine and take action
