Product Requirements Documents bridge user needs, business goals, and technical feasibility. Vespper helps you draft PRDs that connect every requirement to its source — user research, technical constraints, or business objectives.
1. Requirements Documentation Standards
Product requirements must be documented following established engineering standards to ensure completeness, consistency, and testability.
IEEE 29148:2018
- Requirements engineering — lifecycle processes and documentation standards
- Requirement characteristics: necessary, unambiguous, measurable, achievable, verifiable, traceable
- Requirements specification document structure and content guidelines
User Story and Acceptance Criteria
- INVEST criteria for well-formed user stories (Independent, Negotiable, Valuable, Estimable, Small, Testable)
- Gherkin syntax (Given/When/Then) for behavior-driven acceptance criteria
- Definition of done standards linking requirements to test cases
- Ambiguous requirements are the leading cause of development rework and scope disputes
- Requirements without acceptance criteria cannot be objectively verified as complete
2. Regulatory Requirements Integration
Products subject to regulatory requirements must incorporate compliance needs into product requirements early in the development cycle.
Accessibility and Privacy by Design
- WCAG 2.1 and Section 508 accessibility requirements for digital products
- GDPR Article 25 data protection by design and by default requirements
- EU Accessibility Act requirements for products and services
Security Requirements
- OWASP ASVS (Application Security Verification Standard) requirements integration
- NIST SP 800-53 security control requirements for federal systems
- EU Cyber Resilience Act requirements for connected products
- Regulatory requirements discovered late in development create costly rework and launch delays
- Privacy by design requirements must be documented at the PRD stage — retrofitting is significantly more expensive
3. Product Safety & Compliance
Connected and physical products must address safety and market access requirements in their product requirements.
Market Access Requirements
- CE marking requirements for products sold in the European Economic Area
- FCC Part 15 compliance for wireless-enabled products
- Consumer product safety documentation for CPSC-regulated products
- Missing compliance requirements in the PRD lead to product redesign after certification testing fails
- Safety requirements not captured at the PRD stage create liability exposure in the final product
4. Traceability & Verification
Requirements must be traceable from source through implementation to verification to manage scope and demonstrate completeness.
Requirements Traceability
- Requirements Traceability Matrix (RTM) linking user needs to requirements to test cases
- Bidirectional traceability enabling impact analysis when requirements change
- Verification and validation planning tied to specific requirements
- Change impact analysis documentation for requirement modifications
- Missing traceability makes it impossible to verify that all requirements are implemented and tested
- Requirements changes without documented impact analysis propagate defects through the system
What happens when documentation falls short
- Product development delays from ambiguous or incomplete requirements
- Compliance failures discovered late in development cycle requiring costly rework
- Feature scope disputes from unclear acceptance criteria
- Regulatory launch delays from unaddressed compliance requirements
- Costly rework from untraced requirement changes propagating through implementation
