When command is transferred in the Incident Command System, it is essential to conduct a briefing. This process ensures that the incoming Incident Commander receives a clear and comprehensive understanding of the incident's current status, operational plans, and any pertinent issues that have arisen. The briefing provides crucial context, including updates on the situation, resources in use, and the tactics being employed, which allows for a seamless transition and continuity of leadership.

The briefing is a vital component of the command transfer, as it promotes situational awareness for the new commander and enables them to effectively make informed decisions moving forward. It establishes a common operational picture and aligns all involved parties on objectives and strategies.

While an assessment, summary, and evaluation might seem relevant, they do not specifically address the immediate need to convey detailed information and operational specifics that support effective command transfer. Thus, the focus on a briefing is what makes it the correct choice in this context.
