While many vendors have taken Apple's mobile management functionality and delivered excellent solutions, each of them has essentially the same set of capabilities - those that Apple permits. That means keeping pace with the needs of the IT community is limited to what Apple chooses to provide.
It's hard to judge whether Apple is going to innovate in its mobile management capabilities -- or at least catch up to the industry. The company has been pretty tight-lipped about iOS 6 in the enterprise, meaning we could see some really progressive features when iOS 6 ships or we could see a very limited range of enhancements.
At this point, the best many companies can do is to look at what's new in iOS 6 and develop policies around options like the Do Not Disturb feature or Siri's expanded capabilities. Hopefully, Apple will at least deliver the functionality to enforce those policies.
