The hard part of the equation is that you must start with Belief. That’s why so much of the Agile literature and practice revolves around “self-organized” teams.
In other words, the team members themselves decided that (based on their belief in the value proposition for the customer) this product was worth delivering and that they wanted to be a part of that process.
Simple ≠ easy. This is hard to scale.
It takes time, commitment, and a willingness to fail far more than you succeed at an enterprise level for a longer period of time than most executives are comfortable with.
However, the payoff in the long-term is immense. You build a nearly unbeatable brand with team members who are passionate, loyal, and committed.
If you are starting your agile journey, I encourage you to go this route… takes longer, costs more, pays off huge in the end.
