PRD

Master this essential documentation concept

Quick Definition

Product Requirements Document - a comprehensive document that outlines all aspects of a product including features, specifications, technical implementation details, and success metrics.

Understanding PRD

A Product Requirements Document (PRD) serves as the strategic blueprint that guides documentation teams in creating user-focused content. It bridges the gap between business objectives and user needs, providing documentation professionals with essential context for crafting effective product documentation.

Key Features

  • User personas and target audience definitions
  • Functional requirements without technical specifications
  • Success metrics and acceptance criteria
  • User journey mapping and workflow descriptions
  • Business objectives and product goals
  • Constraints and assumptions that impact user experience

Benefits for Documentation Teams

  • Provides clear direction for content strategy and information architecture
  • Ensures documentation aligns with actual user needs and business goals
  • Reduces revision cycles by establishing requirements upfront
  • Facilitates collaboration between product, engineering, and documentation teams
  • Creates a single source of truth for product functionality and scope

Common Misconceptions

  • PRDs are not technical specifications or implementation guides
  • They don't replace user research or usability testing
  • PRDs aren't static documents - they evolve throughout product development
  • They don't dictate documentation format or delivery methods

Turning PRD Video Walkthroughs into Actionable Documentation

When developing new products, your team likely creates detailed Product Requirements Documents (PRDs) to guide the development process. These PRDs are often explained through video walkthroughs where product managers highlight key features, user stories, and technical specifications for the engineering team.

However, video-based PRD explanations present challenges for development teams. Engineers frequently need to rewatch lengthy segments to find specific requirements, stakeholders struggle to quickly reference particular specifications, and important details can get lost in long recordings. This inefficiency slows down your development cycle and can lead to misaligned expectations.

Converting your PRD video walkthroughs into structured documentation creates a searchable, scannable reference that development teams can easily navigate. When a frontend developer needs to verify UI requirements or a QA specialist needs to check acceptance criteria, they can quickly find the exact information without scrubbing through video timestamps. Your PRD becomes more accessible and actionable when its contents are transformed into well-organized documentation with tables, checklists, and requirement hierarchies.

Real-World Documentation Use Cases

API Documentation Planning

Problem

Documentation teams often create API docs that focus on technical details without considering actual developer workflows and use cases

Solution

Use PRD to identify key developer personas, their integration goals, and success criteria before writing API documentation

Implementation

1. Extract developer personas from PRD 2. Map API endpoints to user goals defined in PRD 3. Prioritize documentation sections based on PRD requirements 4. Create code examples that align with PRD use cases 5. Structure content hierarchy around user workflows, not technical architecture

Expected Outcome

API documentation that guides developers through real-world implementation scenarios, reducing support tickets and improving developer adoption

Feature Documentation Prioritization

Problem

Limited resources require documentation teams to prioritize which features to document first, often leading to coverage gaps

Solution

Leverage PRD requirements and success metrics to create a documentation priority matrix based on user impact and business value

Implementation

1. List all features mentioned in PRD 2. Score each feature based on user impact metrics from PRD 3. Consider implementation timeline and complexity 4. Create documentation roadmap aligned with PRD milestones 5. Establish review checkpoints tied to PRD success criteria

Expected Outcome

Strategic documentation coverage that supports high-impact features first, maximizing user success and business outcomes

User Onboarding Content Strategy

Problem

Onboarding documentation often mirrors product navigation rather than addressing user mental models and actual workflow needs

Solution

Design onboarding content structure based on user journeys and success criteria outlined in the PRD

Implementation

1. Extract user personas and their primary goals from PRD 2. Map onboarding steps to PRD-defined user workflows 3. Identify key 'aha moments' from PRD success metrics 4. Create progressive disclosure content strategy 5. Align onboarding checkpoints with PRD acceptance criteria

Expected Outcome

Onboarding documentation that reduces time-to-value and increases user activation rates by following natural user progression patterns

Cross-Team Documentation Alignment

Problem

Multiple teams create conflicting documentation that confuses users and creates maintenance overhead

Solution

Establish PRD as the single source of truth for all teams creating user-facing content

Implementation

1. Create shared PRD access for all documentation stakeholders 2. Establish PRD review checkpoints in documentation workflows 3. Map content ownership to PRD functional areas 4. Implement content review process against PRD requirements 5. Create shared terminology and messaging guidelines from PRD

Expected Outcome

Consistent, aligned documentation across all touchpoints that reinforces the same user mental model and product understanding

Best Practices

✓ Establish PRD Review Rituals

Create regular touchpoints with product teams to review PRD updates and understand their implications for documentation strategy

✓ Do: Schedule monthly PRD review sessions with product managers, create change notification systems, and maintain a PRD changelog that tracks documentation impacts
✗ Don't: Don't wait for major product releases to review PRD changes, or assume that minor PRD updates won't affect documentation strategy

✓ Map Content to PRD Requirements

Maintain explicit traceability between documentation sections and specific PRD requirements to ensure coverage and relevance

✓ Do: Create a requirements traceability matrix, tag content with PRD requirement IDs, and regularly audit content against PRD updates
✗ Don't: Don't create documentation in isolation from PRD requirements, or assume that technical completeness equals user value

✓ Validate Content Against PRD Success Metrics

Use PRD-defined success criteria to evaluate whether documentation effectively supports user goals and business objectives

✓ Do: Define documentation success metrics that align with PRD goals, conduct user testing against PRD scenarios, and measure content performance against business outcomes
✗ Don't: Don't rely solely on page views or completion rates without connecting them to actual user success as defined in the PRD

✓ Collaborate on PRD User Research

Actively participate in PRD development by contributing documentation insights about user behavior and content effectiveness

✓ Do: Share user feedback from documentation channels, contribute to user persona development, and provide input on user journey mapping
✗ Don't: Don't treat PRD as a one-way information source, or miss opportunities to influence product decisions with documentation insights

✓ Maintain PRD-Documentation Alignment

Establish processes to ensure documentation stays synchronized with PRD evolution throughout the product development lifecycle

✓ Do: Create automated alerts for PRD changes, establish documentation review gates tied to PRD milestones, and maintain version control alignment
✗ Don't: Don't let documentation drift from PRD requirements over time, or skip documentation updates when PRD requirements change
