Sfdipot Product Factors

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%)

The 7 Product Factors

When to Use This Skill

SFDIPOT Analysis Framework

Structure (What the product IS)

Subcategories:

• Code Integrity: Code quality, complexity, maintainability
• Hardware: Physical components, devices, peripherals
• Non-Executable Files: Config, data files, documents
• Executable Files: Binaries, scripts, libraries
• Dependencies: Third-party libraries, external services

Sample Test Ideas:

• Analyze cyclomatic complexity of critical modules; flag functions > 10
• Inject corrupted config file; confirm graceful degradation
• Upgrade dependency version; validate no breaking changes

Function (What the product DOES)

Subcategories:

• Application: Core business features
• Calculation: Mathematical operations, transformations
• Error Handling: Exception management, recovery
• Security: Authentication, authorization, encryption
• State Transitions: Workflow states, data lifecycle
• Messaging: Notifications, events, queues
• Data Transformation: Format conversion, mapping

Sample Test Ideas:

• Submit order with 1000 line items; measure processing time
• Inject SQL in search field; confirm sanitization prevents execution
• Trigger state transition timeout; observe retry behavior

Data (What the product PROCESSES)

Subcategories:

• Input: User input, file uploads, API payloads
• Output: Responses, reports, exports
• Persistence: Database storage, caching
• Storage: File systems, cloud storage
• Boundaries: Min/max values, edge cases
• Validation: Format rules, business rules
• Formats: JSON, XML, CSV handling

Sample Test Ideas:

• Upload 100MB file; confirm chunked processing completes
• Insert emoji in text field; validate storage and retrieval
• Query boundary date (2038-01-19); check timestamp handling

Interfaces (How the product CONNECTS)

Subcategories:

• User Interface: Web, mobile, desktop UI
• APIs: REST, GraphQL, gRPC endpoints
• Integrations: Third-party service connections
• Protocols: HTTP, WebSocket, MQTT
• CLI: Command-line interfaces

Sample Test Ideas:

• Resize browser to 320px width; confirm responsive breakpoints
• Send malformed JSON to API; assert 400 response with details
• Disconnect WebSocket mid-transaction; observe reconnection

Platform (What the product DEPENDS ON)

Subcategories:

• Browser: Chrome, Firefox, Safari, Edge
• OS: Windows, macOS, Linux, iOS, Android
• Hardware: CPU, memory, storage constraints
• External Software: Databases, message queues
• Network: Latency, bandwidth, offline

Sample Test Ideas:

• Execute on 1GB RAM device; profile memory usage
• Run with 500ms network latency; measure user experience
• Test on iOS 15 Safari; validate CSS grid support

Operations (How the product is USED)

Subcategories:

• Common Use: Happy path workflows
• Extreme Use: Edge cases, stress conditions
• User Management: Roles, permissions, profiles
• Admin Operations: Configuration, monitoring
• Recovery: Backup, restore, disaster recovery

Sample Test Ideas:

• Execute 10,000 concurrent user sessions; monitor resource usage
• Revoke admin access mid-session; confirm immediate effect
• Restore from 24-hour-old backup; validate data integrity

Time (WHEN things happen)

Subcategories:

• Concurrency: Parallel operations, race conditions
• Scheduling: Cron jobs, timed events
• Sequences: Order of operations, dependencies

Sample Test Ideas:

• Two users update same record simultaneously; confirm conflict resolution
• Execute scheduled job at DST transition; validate correct timing
• Cancel operation mid-sequence; observe partial state handling

Remember

SFDIPOT ensures comprehensive test coverage by examining products from 7 distinct perspectives. Each category reveals risks that other perspectives might miss. Use domain detection to weight priorities appropriately.
