Few of us get into marketing or sales because we love data. But once we're in those roles, it's clear that we can't do our jobs well unless we get down and dirty with what the data is telling us. Susan's book, Optimizing Sales & Marketing Data, makes you a more effective data user. She takes your hand and talks you through what you need to do, how to do it and why. She also guides you on getting buy-in to support your work, which, as we know, can sometimes be the hardest step. As someone who's used various data sources throughout my career, and in various ways, this book has helped me take a more consistent, measured approach. I'd recommend it to every serious sales and marketing professional, regardless of where they are in their career. Buy it!
