I think the definition of KPI should actually to Key Process Indicator. This subtle change will bring massive benefits to data teams.

First of all by identifying key processes in an organization data helps to create focus. For example if a company is still looking for PMF, data team can help with running multiple experiments.

Second, by measuring key processes through leading indicators data helps to improve these processes. For example in the case above, data team can create a leading indicator for PMF that helps evaluate the performance of the experiments.
