What should formal large-scale incident after-action reviews include?

The correct choice is to utilize a comfortable location without distraction. This aspect is crucial because the environment in which an after-action review is held can significantly impact the effectiveness of the discussion and reflection. A comfortable and distraction-free setting allows participants to focus on the review process, engage in open dialogue, and encourage honest communication. This environment promotes a culture of learning and improvement, as participants are more likely to share insights and experiences when they feel at ease.

In contrast, while involving all agencies and employing a neutral facilitator are important components of a comprehensive after-action review, they do not address the fundamental need for an appropriate environment conducive to constructive feedback. Focusing on identifying personnel who created problems, rather than addressing the incident as a whole, can lead to a blame culture rather than fostering collaborative improvement. Thus, the emphasis on location and comfort plays a key role in the effectiveness of the review process.
