...and the lack of it

I usually say that there is a need to grasp all the ways of communication in a channel strategy. But I also think that you should be flexible enough to deal with different channels in various manners. At work I use a calender in Outlook. I have a cell phone that I syncronize with the computer and it syncronizes entirely. So if I happen to want an alert before a meeting, I will get it both in my computer and in the phone. It is impossible to close the alert function in the phone alone.
