re: How to develop business savvy?

There's no one-size-fits-all response or answer for this, and I think it's because there are many factors in play here. Without knowing you or your industry, it can range from your personality type, experience, and relations with others outside of your company/firm.

There are plenty of books you can pick up, but I'll be direct in saying that you can't just read about it. You have to be intentionally trying to improve this area. Words on a piece of paper are great to spark ideas or to help motivate you, however, you need to step outside of your comfort zone. I do suggest reading books to help with this as I think they are great resources. I just know from experience that it doesn't open doors for the reader, the reader needs to do that him or herself.

That's my best advice for not really knowing what you need from my own experience which I'm still going through.
