What do you mean by saying that something is 'Enterprise Ready'?
Depends where it's coming from. If its a vendor than it generally means "We haven't tested this in an environment anywhere near as large and complex as yours but we are crossing our fingers and hoping it will scale to your requirements". If it comes from your own IT department it generally means "We've tested this as much as we can in a few of our qa environments and it didn't completely blow up. We would like to test it in your production environment please"
