When I do not know if he is gonna pass the mailbox I send him an e-mail. In these e-mails I usually try and lay out road maps of where I am heading and what I have done. The problem with these two methods of communication is that it can take a day or two to get a response. The time spent waiting on a response is wasted. When time and clarity are more important I switch to phone calls.
Phones give a fairly rich medium for communication.
To utilize that medium you have to get the other person on the phone and sometimes that can be a problem. Mr. Tyson and I have face to face meetings three to four times a week. Two problems with these meetings exist the first is that I have to find Mr. Tyson and second his busy schedule dictates that these meetings have to be fast and to the point. This does not leave us much time for discussion or to come to a consensus. But, decisions can be made quickly.
