IIRC the book "How to measure anything" contains some advice like this: https://www.amazon.com/dp/1118539273/

The author also offers webinars, so maybe it was from him: https://www.howtomeasureanything.com

I think it was from a pretty prominent researcher that had a .edu site, but I couldn't find it and I really tried.
