How to take Fashion Photographs for Groups

I had the opportunity to participate in a fashion shoot where I was able to learn a lot about modeling and posing, as well about how we as photographers can lead and direct the models.  What I have struggled with most when taking portraits and fashion shoots, is knowing how to pose a group.  It can be difficult to pose and maintain the attention of the entire group.  People tend to move, and minds wander, so you have to make sure you work quickly and efficiently to get the shot that you want.  Below are the group shots I took of couples and groups:
