Slightly off-topic, but I started thinking "Wait, how do you measure the effectiveness of your communication platform?" It's an interesting question because when communication is effective, there's not much of it, at least relative to the information transmitted. However, you can't just optimise for "not much communication" because that could mean the opposite: your system is so bad that it's not being used at all. So either you have to find a way to measure the amount of information transmitted (and compare it to the effort expended in doing so) or... something else?
