These are the books I've been reading. They are very helpful for bridging the gap between design and business strategies. I hope these books help you bring business strategies to life in a creative way as it helped me.
On my spare time, I've took online marketing courses taught by Wharton Business School on Coursera. Learning more about business on Coursera and Lynda.com is a very enjoyable experience for me.
This documentation is a treasure for me. I learned so much from the real business stories of famous companies like Target, Song Airline and so on. It helps me come up with marketing solutions for current clients.
