Small changes are easy to manage, but when they're on the scale we're seeing now, there is no certainty about when to jump or how high. It's possible that everyone will just muddle along in 2015, but I think we're more likely to see some big changes either in terms of exits/consolidations or new entries that really shake things up. Probably not as confrontational as Uber, but the fundamental challenges facing UC are on the same level.
This is starting to sound like a blockbuster movie script, so I'd better stop now - unless someone wants to bankroll me! A safer bet is to read my December column on UCStrategies, and then tell all of us what you think 2015 holds in store.
