Problem Statement

Current Situation

[Describe the present state: What does the user/business currently do? What tools/processes exist? What are the current limitations?]

Example:

Currently, users manually export data to CSV, then import into a separate tool for analysis. This is error-prone and takes 15 minutes per report.

Functional Requirements

PRD-Scope: What We’re Building

Functional requirements define what the system does. They describe features, workflows, integrations, and user-facing capabilities.

Must Have (P0) - Critical for Launch

These requirements are blocking; the product cannot ship without them.

REQ-F001: [Feature/Requirement Title]

Description:
[Clear, detailed description of the feature. What does it do? How does it work? What triggers it?]

User Benefit:
[How does this solve a user problem or address a business goal?]

Functional Specification:

Inputs:
- [Input 1]: [Description, format, constraints]
- [Input 2]: [Description, format, constraints]

Processing:
- [Step 1]: [What happens]
- [Step 2]: [What happens]

Outputs:
- [Output 1]: [Description, format]
- [Output 2]: [Description, format]

Example Flow:
User uploads CSV → System parses columns → System validates data → 
System displays preview → User confirms → Data stored in database

Acceptance Criteria:

Task Breakdown (for Planning):

Related User Stories: [Story X, Story Y]
Dependencies: [None | REQ-F002 (must complete first) | External Service Z]
Risk/Notes: [Any known challenges or considerations]

REQ-F002: [Feature/Requirement Title]

[Repeat above structure for each P0 requirement]

Should Have (P1) - Important but Not Blocking

These requirements enhance the solution but aren’t critical for launch. If timeline is tight, these are deprioritized first.

REQ-F003: [Feature/Requirement Title]

[Same structure as above]

Nice to Have (P2) - Future Enhancements

These are ideas for future iterations or post-launch improvements.

REQ-F004: [Feature/Requirement Title]

[Brief description; less detail required than P0/P1]

Proposed Architecture (New Components):

[Describe what changes: new services, data stores, integrations]

Technology Stack:

Layer Technology Rationale
Frontend React 18 Component reusability, large ecosystem
Backend Node.js + Express JavaScript full-stack, real-time capabilities
Database PostgreSQL ACID compliance, complex queries
Cache Redis Session storage, rate limiting
Message Queue RabbitMQ Async job processing
Infrastructure AWS EC2 + S3 Scalability, cost-effective
Monitoring Datadog Observability, alerting

Risks & Mitigation

Technical Risks

Risk Likelihood Impact Mitigation Owner
Performance degradation under load Medium High Load test early (Week 3); cache strategy; database optimization Tech Lead
Third-party API reliability issues Low Medium Implement circuit breaker; fallback logic; monitor SLA Backend Lead
Data migration problems Medium High Test migration script on production-size dataset (Week 4); dry run before launch DBA
Security vulnerability in dependencies Low Critical Weekly dependency scans (Snyk); prompt patching; security review (Week 7) Security Team

Business Risks

Risk Likelihood Impact Mitigation Owner
Insufficient user adoption Medium High Launch with beta user group; gather feedback early; iterate based on usage PM
Competitive feature launch Low High Accelerate timeline where possible; differentiate on quality/UX PM
Scope creep during development High Medium Strict scope gate at Phase 1 completion; defer nice-to-haves to v1.1 PM
Key team member departure Low High Document code/decisions; pair programming on critical features EM

Organizational Risks

Risk Likelihood Impact Mitigation Owner
