Continuous Interruptions

e.g.: 3 team, N features, shared build machine with parallel feature tests when the build is broken, everyone gets feedback about the broken build information overload => "it's broken again, but surely not by me" ==> address feedback to specific committer (e.g.: mail/irc only to the committers involved in the changeset that triggered the build) is anyone working on fixing it? => put a sticky on the monitor "I'm fixing it"
