You can gain a lot of insights about people’s mood and reaction to news and disucssions just by watching them.
One habit I have picked up is during the daily standup, instead of watching the person speaking, I look around and watch the other members of the team. If I know the speaker is discussing a topic that’s particuarly relevant for someone, I’ll watch them to try to gauge their response to it.
You can get a sense of how effective the standup is overall simply by watching the faces and responses of the other people in the room. If the team seems bored or restless, then it might be a sign that the format of the standup or the way things are being discussed could be improved. If someone seems to respond negatively to a particular point or topic, you might take a note to catch up with them 1 on 1 after the standup to follow up.
Try it in your next standup; you will likely be surprised what little insights you get out of it.
