Ant Murphy argues that senior product leaders should limit their consumption of product management books. While these books can be valuable for beginners, their utility diminishes as one gains experience. Murphy emphasizes that reading more product books often leads to confirmation bias, where we seek validation rather than challenge our thinking. Instead of focusing on product-centric literature, he encourages leaders to explore disciplines like design, marketing, psychology, and entrepreneurship. This broader knowledge base helps in understanding different perspectives and fosters collaboration within teams. Murphy believes that product management is inherently collaborative, requiring input from various specialties. A deeper understanding of adjacent fields streamlines communication and can accelerate project timelines. He shares that as one approaches higher leadership roles, the emphasis shifts from refining product skills to developing leadership and strategic thinking abilities. It's crucial for product leaders to appreciate the roles of other executives, like the Chief Marketing Officer, to foster effective relationships and drive business success. Although he doesn’t advocate for completely abandoning product books, Murphy suggests a more balanced approach. He limits his own product reading to one out of every ten books and recommends diversifying reading material for fresh insights. He offers a list of impactful non-product books across various categories, highlighting works that have shaped his perspective. This shift in focus can lead to more significant growth and success in a product leader's career.
