This Operational Tier control triangle seeks to ensure the successful deployment, validation, and transition of information systems into the production environment, while minimising risks and ensuring compliance with business, technical, and security requirements, from testing to deployment to decommissioning. This process guarantees smooth system rollout, thorough testing, and secure decommissioning of legacy systems, ensuring minimal disruption and protecting organisational data and assets.

This control rolls down from the Deliver Solution Domain and cascades into: 2.3.1-Implementation Testing, 2.3.2-Solution Deployment, and 2.3.3-Decommissioning control subdomains.
