Last year I attended a 2-day DMA seminar on the topic of “How to Take the Guesswork Out of Marketing,” by Steve Cuno. (The content of the seminar has been captured in his book Prove it before you promote it.) In the seminar, Steve gave example after example of “hard lessons learned” and followed with teachings on how anyone can apply science to marketing in order to enhance creativity, and trade intuition for sound judgment.
