It really isn't something you can study. You have to be constantly absorbing new knowledge. Have a huge amount of past knowledge at your fingertips so when you see something that is isomorphic with something else in the past you can use that knowledge.

To put it more plainly a lot of supposedly "old" business practices turn out to be the best. I keep on seeing people reinventing things that were common in the 1800-1900's and think to myself "Why bother? That's _just_ a $FOO problem.". Stand on the shoulders of those before you and you have a better chance of success.
