Quick answer: I don't know.
I posited this question on Twitter because product management has come up during various financial institution strategic planning sessions. I also don't know of many new banking products since I've been in the business. See my post on that subject here from nearly two years ago.
But product management is a function that is performed, at some level and degree, in most financial institutions. Even if they have no title Product Manager. But if you don't measure product profitability, I'm not certain what financial institutions are managing to.
The video below discusses how Product Managers can use profitability information to improve the profitability of products and ultimately their institution.
How do you do Product Management?
