Which activity is NOT part of the 'Design and Transition' phase?

In the 'Design and Transition' phase of ITIL 4, the focus is primarily on activities associated with the development and deployment of new or changed services. This includes tasks such as designing new services, planning how these services will be transitioned into operation, and assessing the risks associated with the services being introduced.

Resolving service tickets pertains to the operational phase of service management, where ongoing support and incident management occur. This activity is part of the Service Operation lifecycle rather than the Design and Transition phase. Therefore, it does not align with the objectives of the Design and Transition phase, which is dedicated to ensuring that new services are properly designed and ready for implementation rather than dealing with issues that arise from services already in operation. Recognizing the distinct objectives of each phase is critical in understanding service management best practices.
