Tried this at numerous companies, small and large.

The engineers get this, or are willing to learn. Some (by no means most) scrum/agile leads get it.

The problem is the 'product class' don't get it, aren't interested and by-and-large don't have the aptitude to understand. Try tp explain cycle time, or cumulative flow diagrams to a Product Manage, Product Owner, Service Owner and they most often just brush it away as 'a technical thing'

The problem only gets worse as the Peter principle begins to kick in and thin out the talent towards the top end of the org.
