Marty Cagan's working definition of a product manager, offered in explicit contrast to what's taught in a CSPO (Certified Scrum Product Owner) class: someone who deeply knows the customers, deeply knows the data, deeply knows the business and industry — and constantly works to create value for both customers and the business.
"Behind every product you'll find someone that deeply knows the customers, that deeply knows the data, the business... and that they are constantly working to create value for your customers and for your business — that's what a product manager does."
This is a competency claim, not a title claim — see 'Product Owner' Should Never Be a Standalone Job Title for Cagan's rejection of "product owner" as a standalone job. It underlies why the Product Model (vs. Roadmap Model) PM role carries accountability for value and viability, not just backlog management.
