They're just these deer that were caught in a flash, had never been seen before, and they were clearly shocked, and hence deer in the headlights.

So it's fascinating to me that organization always embraced innovation, and today has the largest following in the digital world on social media.

No other organization comes close.

So why is it that smart executives find reasons not to see the meteor? And what can we do to become more sensitive and more aware of the potential meteors for our organizations?

So Marcus, I know it's been a few years, but can you recall what the team structure looked like at T-Mobile and how you situated everyone, including how you fit in the chief of staff role?

Mm, absolutely, yes.

So the first thing to say is that for me, the chief of staff, um, is really a critical role as part of a leadership team.

And so, um, in my mind, whilst I had a number of direct reports who were all VPs or SVPs, so senior execs who ran large teams, the chief of staff was really there to act as a force multiplier, not only to help me do a better job of the things that I was doing, but also to coordinate across that wider team.

Um, and in this specific example, where we're talking about Adam, clearly his leadership expertise and, um, you know, bringing that fantastic background, being a veteran of the US Marine Corps, he really helped to organize that team.

And so it varies.

Many people have different approaches to how a chief of staff works, but for me it is very much that almost like a deputy who is there to act as a force multiplier, help the rest of the team to maximize its impact and output, whilst at the same time having some special responsibilities.

And what would you say the main benefit of having a chief of staff was? If you were talking to another executive thinking about bringing on this type of role, what would you say, "Here's the main thing I got out of having a chief of staff"?
