John Cutler argues that organizations measuring AI success often fixate on the wrong denominator, counting outputs or usage rather than the outcomes that actually matter. The piece is framed around a simple model for evaluating AI impact in an organization. The stakes are high because teams can appear busy and productive with AI while delivering little real value. Getting the denominator right determines whether AI investment is judged honestly. Since the source text provided is only a single sentence, this metadata reflects the title and framing rather than detailed content.

  • Use a simple mental model to align teams on what AI success means before measuring it.
