The Marshmallow Challenge is a demonstration of how powerful iterative project development can be. Kids are less afraid to fail because they don’t see it as a test, they see it as a challenge. Recent B-school graduates sees this as code for, “You are going to be CEO of Marshmallow Spaghetti Corporation. Proceed.” They shy away from prototypes, whereas kindergarteners are happy to try, note what works, and then proceed. Redefine failure for your team and encourage iterative development for project success.
