Why is it advisable to instruct the group to hold questions until the end of the order?

Instructing the group to hold questions until the end of the order ensures that the presentation maintains a cohesive flow. When questions are permitted throughout a briefing or discussion, it can lead to interruptions that disrupt the speaker's train of thought and make it difficult for all participants to follow the full set of information being conveyed. By reserving questions until the end, the instructor can present a complete and structured overview before fielding inquiries, allowing for a clearer understanding of the material. This approach also helps to ensure that all key points are covered before participants seek clarification, which can enhance overall comprehension and retention of the information presented.
