There are 3 main stages in Disney’s Creative Strategy:
- Focus on creativity: share creative ideas and solutions without worrying about how they would get implemented. (Perhaps try the 100 Post It technique—everyone puts one idea per Post It in a brief, though maybe slightly too-long, period. This quickly surfaces the obvious ideas but also pushes people to get creative)
- Focus on reality: how to turn the idea into an action plan with measurable success metrics
- Focus on critique: what could go wrong, what could be difficult to implement, what’s missing etc
One team could perform all three stages, or you could assign one team per stage, or have two teams go through all 3 stages and compare the results.
