If you have various groups working a problem and they don't communicate, they are significantly disadvantaged relative to groups that talk. Each of these groups have their particular specialties, and it could only be beneficial for them to communicate. Now whether this communication is THE standout factor preventing attacks...that seems a stretch.

I would counter that being in the loop on everything adds a lot of noise and decreases your focus (because you have much more to look at) possibly making you less effective. Communication is hard.

A fair point. I assumed with the article that the communication is working to some extent. I have no way of knowing whether that is indeed the case.
