David Epstein's book *Range* shows that breakthrough innovators often switch disciplines. By entering a new field "through the side door," they bring different mental models and "far analogies" that allow them to see solutions incumbents cannot.

True innovation stems from cognitive and interest diversity. Pairing passionate people from disparate fields—like AI and cheese—sparks more creative conversations and breakthroughs than grouping people with similar interests, which merely creates an echo chamber.

Career growth isn't just vertical; it can be more powerful laterally. Transferring skills from one industry to another provides a unique perspective. For example, using music industry insights on audience behavior to solve a marketing challenge for a video game launch.

A non-linear career across varied industries isn't a weakness but a strength. This 'jungle gym' path sharpens a product manager's core toolset by forcing them to apply fundamental principles to new problems, much like a doctor specializing in different fields to become a better diagnostician.

While domain experts are great at creating incremental improvements, true exponential disruption often comes from founders outside an industry. Their fresh perspective allows them to challenge core assumptions and apply learnings from other fields.

To break free from industry conventions, prompt teams to examine how unrelated industries have solved similar problems—like how thermostats evolved from simple dials to Nest. Posing questions like, "What if Apple designed our product?" can spur truly novel thinking.

PMs who transition from other professions bring life skills that help them understand diverse perspectives. This real-world experience builds more empathy than academic product management programs, which primarily teach frameworks and a common language.

Product management "range" is developed not by learning domain-specific facts, but by recognizing universal human behaviors that transcend industries—the desire for simplicity, convenience, or saving time. Working across different verticals hones this pattern-matching skill, which is more valuable than deep expertise in a world of accessible information.

Instead of seeking inspiration from disparate fields, 'fractal' down your own supply chain. A fashion designer meeting the sheep herders or a marketeer meeting the suppliers' supplier can uncover deep, relevant insights that spark powerful, practical innovation within your own domain.
