A choir keeps a chat helper because members who use it renew next season at a higher rate than members who do not. The board is not judging the helper by one-session novelty. Which metric justifies keeping it?
Select an answer to reveal the explanation.
Short Explanation
Think of members who chat and then renew next season more often. That is customer lifetime value. One-session novelty, a drawing RMSE, and a token bill with no renewal link do not keep the helper.
Full Explanation
Customer lifetime value captures retention over time, here a higher next-season renewal among chat users. One-session novelty is not that retention. RMSE on a drawing and a token invoice without a renewal link do not justify keeping the helper.
