This activity verifies the integrity of the solution under deployment and transitions the new changed service to Service Operations.

Integrity testing can include the following items:

• Service assets and capabilities are in place
• Documentation updates are completed
• Learning material has been made available to stakeholders
• Users are prepared to operate the new or changed service
• Measurements and reporting systems are established.

Transition to full service status can include a defined period as early life support; defined by ITIL® as "Support provided for a new or Changed IT Service for a period of time after it is Released. During Early Life Support the IT Service Provider may review the KPIs, Service Levels and Monitoring Thresholds, and provide additional Resources for Incident and Problem Management."¹
