The article has just been published. "KORE" is only covered in a short paragraph toward the end. I paraphrased that funky question to: "Is the customer achieving the goals they expected with/from your product?"
Great article, Miles Goldstein! My previous company did exactly what you're saying not to do - we over-emphasized CSAT, AHT, FCR etc. without digging into the details and did not define clear outcomes.
