Quality Requirements

Quality Tree​

The following quality attributes are critical for the success of the 1+MG Node.

Quality AttributePriorityMotivation
SecurityCriticalHandling sensitive genomic data requires strict adherence to GDPR and National Laws.
InteroperabilityHighThe system must function within a European Federation (27+ countries).
UsabilityHighThe application process must be transparent for researchers.
PerformanceMediumDiscovery queries should be interactive; Compute jobs can be batch/long-running.

Quality Scenarios​

These scenarios map to the Sequence Diagrams in the Runtime View.

QS-01: Secure Computation (Security)​

  • Scenario: A researcher executes a workflow on sensitive data.
  • Stimulus: Submission of a WES request.
  • Response: The system verifies the GA4GH Passport. The compute node has NO internet access. Data is encrypted at rest.
  • Measurement: No data exfiltration possible. Compliance with "Five Safes".
  • Link: Runtime View -> Secure Processing Workflow

QS-02: Cross-Border Discovery (Interoperability)​

  • Scenario: A central query is distributed to 27 national nodes.
  • Stimulus: "Does any node have BRCA1 variants?"
  • Response: All nodes respond with a count (or error) within 10 seconds.
  • Measurement: 95% success rate. Standardized Beacon v2 response format.
  • Link: Runtime View -> Data Access Workflow

QS-03: Data Sovereignty (Compliance)​

  • Scenario: Additional data access restriction (Veto).
  • Stimulus: A valid Central DAC approval is received by a National Node.
  • Response: The National Node (Data Holder) re-evaluates the request against local law and may Veto the access.
  • Measurement: Access is DENIED locally despite Central approval.
  • Link: Runtime View -> Data Access Workflow

QS-04: Operational Compliance (Maintainability)​

  • Scenario: New staff member joins the Node.
  • Stimulus: Onboarding process initiation.
  • Response: Staff is trained on "EU-wide SOPs" and "Node-specific SOPs" within 2 weeks. Training is recorded.
  • Measurement: 100% of staff have valid Training Records (Annex 1 of MS13).
  • Link: Building Block View -> Management Zone

QS-05: Service Management (Compliance)​

  • Scenario: Annual Compliance Assessment.
  • Stimulus: Audit by GDI Operations Committee.
  • Response: The Node demonstrates adherence to FitSM standards and has a valid "Compliance Assessment Report".
  • Measurement: 0 Major Non-Conformities.
  • Link: Risks -> TR-02 Compliance Maturity
