Great product managers, per these sources, are judged by business outcomes and value/viability ownership rather than feature output or backlog administration. Marty Cagan says the product manager's job is to ensure what gets built is both valuable and viable, not just executed from a backlog47, and he profiles strong PMs as smart, creative and persistent people who think beyond features to solve business problems8.
01Core knowledge and skills
- Cagan argues a PM must be an acknowledged expert on customers, data, their own business, the market, and the product itself4.
- Cagan and Bob Baxley describe this as "product sense," a range of customer, data, market, business and product knowledge that others on the team typically lack6.
- Cagan says a great PM must deeply understand the business and its constraints, including financial, sales, legal and technical, without needing an MBA8.
- Hiten Shah's analysis of 51 job postings found empathy with customers is among the most sought-after personal skills, and that fewer than half of roles expect PMs to conduct customer research5.
02Leadership and team building
- Cagan says leadership separates great product people from merely good ones, so PMs should lead regardless of title8.
- Marty Cagan's advice for managers is to hire people smarter than yourself and help them succeed3.
- Cagan recommends a monthly development review focused on the three largest skill gaps1.
