Advanced Requirement & Quadrant Diagram Examples

Requirement Diagrams

1. Authentication System Requirements

requirementDiagram

    requirement Auth_Req {
        id: REQ_AUTH_001
        text: System shall support OAuth2.0 authentication
        risk: medium
        verifymethod: inspection
    }

    requirement Session_Req {
        id: REQ_SESS_002
        text: Session timeout after 30 minutes of inactivity
        risk: low
        verifymethod: test
    }

    element Auth_Service {
        type: Software
    }

    element Session_Manager {
        type: Component
    }

    Auth_Service - satisfies -> Auth_Req
    Session_Manager - satisfies -> Session_Req

2. Payment Processing Requirements

requirementDiagram

    requirement Payment_Req {
        id: "PAY-001"
        text: Process transactions within 2 seconds
        risk: high
        verifymethod: test
    }

    requirement Security_Req {
        id: "SEC-002"
        text: Encrypt all payment data in transit
        risk: high
        verifymethod: test
    }

    element Payment_Gateway {
        type: ExternalService
    }

    Payment_Gateway - contains -> Payment_Req
    Payment_Gateway - satisfies -> Security_Req

3. Logging System Requirements

requirementDiagram
    
    requirement Log_Format {
        id: "LOG-101"
        text: Logs must be in JSON format
        risk: low
        verifymethod: inspection
    }

    requirement Retention_Policy {
        id: "LOG-102"
        text: Maintain logs for 90 days
        risk: medium
        verifymethod: inspection
    }

    element Logging_Service {
        type: Microservice
    }

    Logging_Service - traces -> Log_Format
    Logging_Service - copies -> Retention_Policy

Customization Tips:

1. Requirement Diagrams:

   • Use different risk levels (low, medium, high, critical)
   • Vary verification methods (test, inspection, demonstration)
   • Utilize relationship types: contains, copies, derives, satisfies

2. Quadrant Charts:

   • Adjust axis labels to match your context
   • Use meaningful quadrant names
   • Position items using 0-1 scale for both axes
   • Combine with annotations for clarity

Usage Note: These diagrams work best in Mermaid 10.0+ versions. Ensure your rendering environment supports the latest syntax.
