I find mechanisms like this to be silly and childish. We're all adults; part of life is learning how to communicate and how to be heard - more generally, how to function in a group. If you haven't figured out how to function properly to the point that you need a system of hand signals in meetings, then it is worth it to look at why your development has been stunted, perhaps with a therapist.
Similarly to that other commenter who didn't give a reason, I would also immediately start looking for work if my workplace implemented this.
I would probably start looking for somewhere else to work if I had to use special hand signals during meetings.
The hand signal for point of order is very similar to BSL for vagina. I'm not sure they consulted any Deaf people.
The GDS have done some great work. Nice to get a gentle reminder that they're still public sector crazies once in a while. ;)
Personally I think they might be more useful as a secondary bandwidth channel: you can now see, while you speak, if the majority needs the point clarified.
The Lean Coffee hand signals includes a couple others that aren't in this blog post.

Another hand signal I've used in large groups is pointing at a person who has a hand up (wants to say something). It's a useful signal to the person speaking and can avoid people stepping on each other to speak next.
Sounds like an episode of The Office!
Is there a reason they don't use something like parliamentary procedure?
Love the bunny rabbit signal for "disagree". Very cute.
No evidence, no credit!
