Team week as TL

[aussie]

I just wanted to ask, regarding team week, the following:

This question is more relevant to the officer candidate. When appointed to the position of team leader, during team week. What is the best way to manage the task, especially if fatigued, tired and hungry?

The angle I'm coming from is, I find that I need time to process the task, to get my head around the best way to do it. In the meantime, some of the guys have jumped in and started to construct something and are all over it. The issue is that cadre, watching and observing, may perceive the leader to not be in control and to not be leading but rather being lead? Which may negatively impact one's grading as a leader?

What advice do you guys have in this matter?
