In a smaller scale this probably would be very effective, however I can't see this being possible with bigger client volumes. Also, I noticed in my career some sort of elitism and looking at the marketing from above, which is driven by ignorance in most of the cases.
It’s not possible to do this with all clients; that’s not my argument. But in a big company it should be done with as a matter of practise with at least a cohort.
But yes there is a ton of ignorance in this world. I constantly have to remind folks that the world outside of Spreadheets is insanely messy.
