As most enterprises lack a way to measure whether their contact center AI is working, this article examines TELUS Digital's "agent performance loop" framework, which connects training, real-time agent assist, and quality monitoring so insight from each stage improves the other two. Erin Walker, Global VP, CX AI, Business and Delivery at TELUS Digital, outlines the three conditions that determine whether agent assist survives production — native CRM integration, low-latency recommendations and a feedback loop that captures agent signals at scale — and explains why agents abandon AI tools not because the model is bad, but because it learned from the wrong data.
