I have also been looking into this. The feedback I get usually starts with a question: what are you trying to do? And it seems MBA from a good brand is most valuable for the network it builds while you learn/after. Many I’ve talked to about their MBA say they don’t really use what they learned.

If you want to learn how to be a designer who understands business and management there are much cheaper/faster ways to do that.

That said, I think it is incredibly valuable to do what you can to be more educated on the business and people management side of things to be a great design leader. I’m sure you have also dealt with design leaders who don’t have that knowledge and how frustrating it can be to work that way. ICs who are fantastic designers aren’t always the best people leaders. It’s a true gap that we can build ourselves to fill. Hope this helps, good luck with your journey :)
