PRD QA Enricher

Add Quality Requirements and Acceptance Criteria to a Phase PRD, preparing it for test planning.

Inputs Required

Phase PRD — With R-nnnn requirements (use prd-phase-generator first if missing)

Workflow

Audit for Quality Requirements — Identify missing non-functional concerns
Add Q-nnn entries — Security, performance, accessibility, etc.
Write Acceptance Criteria — Happy path, edge cases, error conditions for each R-nnnn
Update traceability — Link ACs to requirements

Step 1: Quality Requirements Audit

Review the Phase PRD and ask: what cross-cutting concerns are missing?

Quality Categories Checklist

Tag	Category	Questions to Ask
`[PERF]`	Performance	Response times? Throughput? Caching?
`[SEC]`	Security	Auth? Input validation? Data protection?
`[AVAIL]`	Availability	Uptime requirements? Failover? Recovery?
`[SCALE]`	Scalability	Concurrent users? Data volume limits?
`[ACCESS]`	Accessibility	WCAG level? Keyboard nav? Screen readers?
`[COMPAT]`	Compatibility	Browsers? Devices? Integrations?
`[I18N]`	Internationalization	Languages? Locales? RTL support?
`[API]`	API Standards	Versioning? Rate limits? Error formats?

Writing Quality Requirements

Q-007 [COMPAT]: The system shall support Chrome, Firefox, Safari, and Edge (latest 2 versions)

**Applies to:** F-001, F-002, F-003
**Priority:** Must

Each Q-nnn should:

Have a category tag in brackets
List which features it applies to
Be testable and specific

Step 2: Acceptance Criteria

For each R-nnnn, write AC-nnnn entries covering:

Coverage Categories

Happy path — Normal successful flow
Edge cases — Boundary conditions, limits, empty states
Error handling — Invalid input, failures, recovery
State transitions — Before/after, concurrent access

AC Format

**Acceptance Criteria:**
- AC-R0142-01: Form accepts valid email formats (user@domain.tld)
- AC-R0142-02: Form rejects invalid emails with inline error message
- AC-R0142-03: Form requires non-empty name field
- AC-R0142-04: Form preserves input on validation failure
- AC-R0142-05: Submit button disabled until required fields populated

AC Writing Guidelines

Do	Don't
Specific, testable conditions	Vague ("works correctly")
One behavior per AC	Multiple behaviors combined
Observable outcomes	Implementation details
Include error states	Only happy path

Typical AC Count

Simple requirement: 2-3 ACs
Standard requirement: 3-5 ACs
Complex requirement: 5-8 ACs

If a requirement needs >10 ACs, recommend splitting the requirement.

Step 3: Update Traceability

After adding ACs, update the Traceability Matrix:

Requirement	Feature	Priority	Status	AC Count
R-0142	F-014	Must	Draft	5

Quality Requirements Numbering

Q-nnn is sequential across the entire product (like R-nnnn). Check previous Phase PRDs for last used Q-nnn.
