There should be a word for people who have the annoying tendency to point at problems and talk about them, instead of trying to actually improve the situation (or maybe there is, and I just don’t know it).  I don’t know if you’ve been in a meeting with one of these people, but it’s so frustrating to listen to someone pontificate on and on about some problem and how it’s SO horrible, without trying to come up with any ideas, or asking someone to help them solve the problem, or just stop talking about it so someone else can try to solve the problem.

I’m not saying you should wait to bring a problem to your boss until you have a solution — for some teams/problems that’s a good idea, and for others that’s a horrible idea, and you need to get help for problems.  But what I am saying is that you should focus your attention and energy on fixing the problem, or removing the problem, or getting around the problem, or changing the situation so it’s not a problem anymore, or something else productive.
