SFDIPOT Product Factors Analysis

<default_to_action> When analyzing requirements:

1. IDENTIFY document type (epic, user story, spec, architecture doc)
2. DETECT domain context (ecommerce, healthcare, finance, etc.)
3. ANALYZE each SFDIPOT category systematically
4. GENERATE test ideas with action verbs (no "Verify" patterns)
5. ASSIGN priorities (P0-P3) and automation fitness
6. SURFACE clarifying questions for coverage gaps
7. OUTPUT in requested format (HTML, JSON, MD, Gherkin)

Quality Gates:

• Human exploration >= 10%
• No "Verify X" test patterns
• Priority distribution: P0 (8-12%), P1 (20-30%), P2 (35-45%), P3 (20-30%) </default_to_action>

Quick Reference Card

The 7 Product Factors

Factor	Question	Example Focus Areas
Structure	What IS it?	Components, code, dependencies
Function	What does it DO?	Features, calculations, errors
Data	What does it PROCESS?	Input, output, persistence
Interfaces	How does it CONNECT?	UI, API, integrations
Platform	What does it DEPEND ON?	OS, browser, hardware
Operations	How is it USED?	Workflows, admin, recovery
Time	WHEN do things happen?	Concurrency, scheduling

When to Use This Skill

Scenario	Priority	Output
New epic planning	High	Full SFDIPOT assessment + test ideas
Sprint requirement review	Medium	Targeted analysis + clarifying questions
Test strategy definition	High	Comprehensive test coverage plan
Risk assessment	High	Domain-weighted priority assignment
Coverage gap analysis
