Team building seminars take a lot of time and effort. Some companies even host weekend parties just to make close-knit teams that are more efficient in the long run. Those are great and all but there are other activities that take less time and take out the stiffness right before an important meeting.
Bingo Playing a round of bingo before a meeting will help things stay light and easy. We all know how wound up and nervous people are right before a meeting. Get creative with how you play your round of bingo to change things up a bit.
Game Show Another idea is to mimic a currently popular game show. This will help build team rapport right when you need it.
