Marty Cagan

Marty Cagan is an American product management author and advisor whose Inspired is widely considered the defining guide to building technology products in empowered, modern product organizations.

Marty Cagan spent decades as a product leader at companies including Hewlett-Packard, Netscape, and eBay before founding the Silicon Valley Product Group, through which he has coached product teams at major technology companies around the world. Inspired, first published in 2008 and substantially revised in 2018, is the accumulated framework of that experience: a systematic argument for how technology product companies should discover, define, and deliver products that customers actually want.

The book’s central distinction is between what Cagan calls “feature factories” — organizations where product managers write requirements based on stakeholder requests and measure success by feature delivery — and genuinely empowered product organizations where cross-functional teams are given problems to solve rather than features to build. Cagan argues that most technology product organizations operate in the first mode despite believing they operate in the second, and the book provides specific frameworks for assessment, transformation, and the practices that distinguish strong product management from mere project management.

Inspired is occasionally criticized for its Silicon Valley-centrism — the model assumes conditions (access to talent, organizational appetite for autonomy, access to customers) that don’t always exist, and practitioners in regulated industries or large enterprises sometimes find the prescriptions aspirational rather than immediately applicable. The revised 2018 edition addressed some of these criticisms but remains most directly useful for technology product teams in growth-stage companies. For product managers who want a clear, opinionated framework for their craft, there is no more important book in the field.
