Revenue & Profit To Measure VMS Companies

Hi all, I've read a lot of discussion related to merger, take over and many other "artistics strategics & announcement" to said how to solve this new challenge in the industries. Today with pricing drops, more competitors, less revenue for integrators, and all for the same market size... (than last years, at least)

Have anybody build a revenue&profit index to understood who is big, who is not, who is profitable and who is not.

I know, is not an easy way to fully understood the VMS market status today, but cold be a useful tool to select a VMS partner for the next 5 years
