Crazy 8’s is a core sprint method. It’s a fast sketching exercise that challenges people to sketch 8 ideas in 8 minutes (not 8 variations of one idea or 8 steps of one idea, but 8 distinct ideas). The goal is to push beyond your first idea, which is frequently not the most innovative, and generate a wide variety of solutions to your challenge.
This method could be use online - if needed.
In that case participant need to provide their own paper, and drawings should be shared via a video-conferencing tool.
Alternatively - each participant could be assigned a section on an online collaboration whiteboard (Miro/Mural) and people draw their ideas online. In that case a video-conference is still needed to provide explanations afterwards.
