Agile evangelists must learn how to manage expectations prior to the adoption of Scrum. These expectations will be about the outcome of adopting Scrum, the predictability of the model, the attitudes towards it and the involvement it takes. Understanding the foundation of Scrum and the components such as the new teamwork model, the new roles Scrum requires, how to scale the process and ways to grow even more agile as time goes on are crucial in becoming an effective agile evangelist for a company.
