Not sure about that. I'm not familiar with Apple's DRI concept. But it sounds like there could be a DRI for the tech and a DRI for the business side of things.

If not you would probably want the tech role to be the DRI and pull the info from the business/product expert. The alternative would be to have the business/product expert be the DRI and maybe take on a project manager type role. There is also the possibility that someone does do both roles and is super efficient, or just works 100+ hours per week. But in reality my guess is they end up becoming the business/product expert and delegating the tech lead to someone else
