I almost always do the Myers Briggs Type Indicator test with teams that I have. It's an easy and fun way to learn about each other, and yourself, and how the team interacts with each other. We talk about each of the four pairs of letters, what they mean and what teams specifically have conflict around. We also pass around the chart, filling in your name in your block, until everyone has everyone elses type on their chart.
When and where.
+ Theme brainstorming
What kind of theme could ground the whole experience and how could we expand on that theme if needed. And how could we provide some advance promotion to this experience? And how could we add in just pure fun activities based on this theme.
Oh and we watched this promo thing from Hungary 2008. Wow.
