What is Product Management?
Product Management is the function responsible for defining what to build, for whom, and why — then ensuring it gets built, launched, and iterated on to maximize business value.
Product Management is the function responsible for defining what to build, for whom, and why — then ensuring it gets built, launched, and iterated on to maximize business value. Product managers (PMs) sit at the intersection of business, technology, and user experience.
Core PM activities: customer research, market analysis, prioritization (RICE, WSJF), roadmapping, writing requirements (PRDs, user stories), collaborating with engineering and design, launch coordination, and metrics analysis.
In the AI era, PMs must also understand AI unit economics, the Cost of Predictivity, and the trade-offs between AI-powered and deterministic features.
Why It Matters
Product management determines what engineering builds — and therefore how engineering capital is allocated. PMs who understand product economics prevent the most common form of capital destruction: building features that cost more to maintain than they generate in value.
Frequently Asked Questions
What is the difference between a PM and a project manager?
A product manager decides WHAT to build (strategy, prioritization, requirements). A project manager ensures it gets built ON TIME (schedules, resources, tracking). They are different roles.
