On earning respect of a leadership team made of alpha personalities....

When dealing with a leadership team, it is imperative for a CFO to have respect from the team.  

One way is to engage with each of them at both a professional but also personal level.  Show genuine interest in them personally (families, kids, etc.).  And ensure this interest is sincere.  Care.  Always used that in any engagement (as an icebreaker).  It is also important to develop an ability for them to think you have their back...and in many cases follow through, (if you believe in something they are doing or trying). Lastly, it is important to find something they care about professionally and strive to help them in someway.
