Recover from post-vacation adoption slump
A sign that it was a good vacation is when you return and are unable to remember the passwords for the systems you use at work.
Habits take time to buld. If you are in the process of accelerating adoption of your organization's enterprise social network, be mindful that the northern hemisphere summer poses a particular challenge. There should be no surprise that with people away, the activity level in the network is lower in July and August. The real challenge, however, is to reinforce those useful social habits amongst the crowds returning to work.
Redouble your communications efforts, energize your community managers, sync up with your use case representatives - and remind leadership that you expect them to lead by example.
(And prepare to repeat the exercise in December.)
