If development is in product, how long has development been in product? Is this a recent change where development was transitioned from IT to product during a recent transformation?

Not directed at you, just some general comments.

As someone hinted at in another comment, it seems a better (less dichotomous) framing is:

- tech first (developer lead, selling software or hardware),

- tech enabled (developers are a key collaborator with the business, e.g., logistics, manufacturing, ecomm, marketing, really every company should be), or

- tech as a cost center (the “traditional” company in the article).

What about the trifecta of product, engineering, and design advocated for by Marty Cagan?

I think the same argument that’s being made for giving developers more weight in the development process could be argued equally as well from the side of design.
