I've had the same metric of session duration asked of our usage as well.

When a data flow becomes useful, it also becomes important. Important data flows stop being useful if they break and the user who created it is no longer available. This means that data flows shouldn't be used for anything important due to things like terminations, vacations, sick leave, etc. I don't like tell our users or…

We must limit the use of dataflows in particular for important work due to that work being lost in the event the owner is not available.
