A last-mile delivery company launches an AI chat assistant to help customers track packages and resolve delivery issues. The stated business goal is improving the customer experience, not cutting support costs. Which KPI should the program owner prioritize as the primary success measure?
Select an answer to reveal the explanation.
Short Explanation
The company said the goal was a better customer experience, not a smaller support bill, so your KPI has to measure exactly that. Customer satisfaction score after an AI-assisted interaction asks customers directly whether the help actually worked for them — anything that just counts tickets or dollars is measuring a side effect, not the mission.
Full Explanation
Customer satisfaction score after AI-assisted interactions is the right primary KPI because it measures the thing leadership actually said it cared about: whether customers had a better experience, not whether the company spent less money. Cost per support ticket resolved is a pure efficiency metric — it might drop nicely while customers are quietly annoyed by a chatbot that can't solve their problem, which would be a failure dressed up as a win. Reduction in the number of human support agents needed is even further from the stated goal; headcount changes are a workforce-planning outcome, not evidence anyone's experience improved, and chasing it risks stripping away the human escalation path customers need when the bot fails. Number of support tickets deflected from human agents is the trickiest distractor because it sounds customer-facing, but deflection only measures how much work moved away from a person — a high deflection rate paired with frustrated, unresolved customers would still be a failure against the company's own stated objective. None of the cost or volume metrics are worthless; they're legitimate supporting measures for a business case. But when leadership states an explicit goal, the primary KPI has to trace directly back to that goal instead of whichever number is cheapest to report. The operational check: before adopting a KPI, ask whether moving this number proves the stated goal happened — if the answer is "not necessarily," it belongs in the supporting metrics, not the headline.
