I just had my first round of O3's today with my six direct reports.
I've been with the company 3 1/2 years. The entire staff has been there way longer than I have, with the exception of one fellow we hired last month. It felt strange having this "get to know you meeting" with people I've already known so long. (also, we're a small organization. 85 people total, 11 in IT - six of those are mine).
Still, the feedback from more than half the team was "this is great. I am really glad you're doing this. We need this."
Yes, they did last about an hour, so I am glad I left half an hour between each one.
Mark and Mike, you'll be glad to know that I've already sent the manager-tools URL to a friend of mine (we're both former Marines) who's a manager at a large commercial software company.
Thanks a million!!!
