Configuration Audit

  • Purpose: Verifying that configuration items (CI) meet specified requirements, standards, and baselines to ensure system integrity, accuracy, and compliance.
  • How a software team ensures change implementation: Technical review + Configuration audit.
  • Configuration Audit Questions:
    • Did the change meet the ECO (Engineering Change Order) specifications?
    • Were additional changes incorporated?
    • Was the software development process followed and standards adhered to?
    • Have all relevant configuration items been updated properly?
    • Was the change properly accounted for (change date, author, etc)?

Status Accounting

  • Purpose: Tracking, recording, and reporting the status of configuration items to maintain accurate, current information on configuration changes.
  • Typical questions:
    • What happened?
    • Who did it?
    • When did it happen?
    • What else will be affected?
    • It's crucial to ensure traceability throughout the process.

Change Control Board (CCB)

  • Responsible for reviewing, approving, or rejecting change requests.
  • Composition: Project managers, developers, quality assurance (QA) leads, operations teams.
  • Role: Assessing potential impacts, aligning with project goals, ensuring compliance with standards.

Configuration Audit in Change Control

  • Steps: Change request submission, evaluation and impact analysis, approval and decision, implementation, verification and closure.
  • Process: Responsible roles for each step (Manager, Developers, QA). Ensures changes are correctly tracked, compliant and integrated.

Status Accounting in Change Control

  • Purpose: track and report the status of configuration items during a change control process
  • Steps: Change request submission, Evaluation & Impact Analysis, Approval & Decision, Implementation, Verification and Closure
  • Process: Responsible roles at each stage, focusing on traceability, ensure proper management.
