Why do we tell stories? What power lies within storytelling? Why do stories stick and survive over decades in your mind? And why are they used in agile? Why does a project management standard make use of it and what is its effect on the team?
Agile my personal favourites 4 to 6. Organizations with succeeding agile teams have this mindset. It is a thing of trust. Trust in your team, give them an environment and respect it. Give them the tools and resources they need to find the FLOW.
