What Is a Product Requirement? | Vantage
Product Requirement A product requirement is a specific, testable statement that describes a capability, behavior, or quality a product must have. Requirements translate user needs into implementable specifications. They are the bridge between "what the user wants" and "what engineering builds."
Why product requirement matters
Requirements prevent the gap between what was intended and what was built. Without clear requirements, engineers interpret the PRD differently from the PM's intent, leading to rework, missed features, and frustration. Well-written requirements reduce ambiguity and set clear expectations for what "done" means.
How it works
Requirements are extracted from PRDs and user research. Each requirement specifies: what the system must do (functional) or how it must perform (non-functional), the acceptance criteria that define completion, the priority level (P0-P3), and the effort estimate. Requirements are tracked in a backlog and assigned to tickets for implementation.
Common mistakes
Writing requirements as solutions instead of needs ("add a dropdown" vs. "user can select their role")
Vague requirements without testable acceptance criteria
Not prioritizing requirements (everything is P0)
Writing requirements in isolation without engineering input
Not tracing requirements to user needs or business goals

How Vantage relates
Vantage extracts requirements automatically from AI-generated PRDs. Each requirement includes priority, effort estimate, and acceptance criteria. Requirements are then converted to dependency-aware tickets that push to Linear or Jira, creating a traceable path from user need to engineering ticket.
