Our brain is wired for stories. A story is the most effective way to meet our brain somehow contradictory needs of logical sequential reflection ( this happens because of that, then comes other …) and emotional involvment.
If Agile Adoption may turn in circles in your organisation, in spite of all great feed-back and proven evidence , it is mainly because logic, data and information is not enough to take action.
As Dan and Chip Heath say , action is ignited when you speak to your emotions elephant while giving the direction to your rational rider. There nothing better to do both that an involving story. If you want to on-board people in Agile Adoption , you’d better tell a good true story where they can picture themselves as heroes.
