Have you tried Extreme Rock-Paper-Scissors? Ideal for BIG groups, and super easy/funny to run: https://www.icebreakers.ws/large-group/extreme-rock-paper-scissors.html

@Renko P. Exactly! But it only works in really large groups (like +30 people)

Generally just creating an agenda and have a desired outcome set (like IDOARRT, for instance), is already super valuable. Most meetings just 'happen', and people also often leave the meeting without any actionable next steps. Besides that, having a document people could pre-read before joining the meeting - as well as a follow-up document (like a living doc), can't be understated. I can't believe how many companies still operate like this and how much knowledge and decisions just get lost because they weren't documented (also for you as a facilitator, it makes things so much easier). The final thing is that not everything has to be a meeting - so just getting clarity on which kind of gatherings should be meetings (vs. an email, a workshop, an announcement, ...) is also super useful. My 'golden rule' for that is: "is there a group of people that has to decide on something together?" OR "is there a group of people that need to hear each others ideas and find solutions to problems", in 99% of cases (if not 100%), that should be a workshop. All else, it should be something else. And if it should be a workshop, it doesn't mean that it should take long. Just adding basic workshop techniques (such as alone together, brainwriting, ...) to any kind of gathering makes them 10x more valuable and engaging. Hope that helps.
