Designate (randomly or strategically) some members of your group to be on the Red Team and play devil’s advocates to your current plans. Empower them to point out the flaws they see. What vulnerabilities can they exploit? What responses does the Blue Team (believers in the current plan) have to the issues the Red Team surfaces?
In our Virtual Facilitation Guide, we have activities that provide you with step-by-step instructions and everything you need to facilitate Red Team vs. Blue Team in a virtual meeting using Zoom or a platform with similar features.
