What Is a PRD (Product Requirements Document)?
A PRD (Product Requirements Document) is a document that describes what a product or feature should do, who it is for, and why it matters to the business. It serves as the single source of truth that aligns product, engineering, and design teams around a shared understanding of what needs to be built.
Why PRDs matter
Without a PRD, teams rely on scattered conversations, slide decks, and tribal knowledge to understand what they are building. This leads to misalignment, rework, and features that miss the mark. A well-written PRD reduces ambiguity by answering the essential questions before development begins: What problem are we solving? For whom? What does success look like?
PRDs also create a record of intent. When a team revisits a feature six months later, the PRD explains not just what was built but why certain tradeoffs were made. This context is invaluable for onboarding new team members and for making informed decisions about future iterations.
What goes into a PRD
Most PRDs include a problem statement, target audience, goals and non-goals, functional requirements, success metrics, and a timeline. Some teams add sections for competitive context, dependencies, or open questions. The format varies by organization, but the best PRDs share a common trait: they are written for their audience. Engineering-heavy sections use precise language. Executive summaries stay high-level.
The most effective PRDs are living documents. They evolve as the team learns more during development, and they capture the decisions made along the way. A PRD that never changes after its initial draft is either perfectly prescient or, more likely, ignored.

How Vantage relates
Vantage helps product teams create, manage, and share PRDs in one connected workspace. Because Vantage links requirements to decisions, user stories, and engineering tickets, your PRD stays in sync with what the team is actually building. When requirements change, every connected document updates automatically, so nobody works from stale information.
