This activity analyzes each change to determine its impact on existing and planned CIs as well as the impact on resources required to build and deploy the change. This involves identifying the appropriate change model for handling the change, scheduling a CAB meeting if specified by the change model, and obtaining a complete set of analysis results and issues.

In this activity, the impact of a change is evaluated from both the IT and business perspectives, ensuring that the change can be successfully implemented with a minimal impact to committed services and still meet business requirements.

This activity allocates priority based on urgency, and if the change is for the resolution of a problem, the priority will also reflect projected impact. Assessment often assigns impact categorization classes such as minor, significant, or major.
