People who have natural leadership skills and are positive thinkers are well suited for roles in Scrum. Having a role in Scrum usually means you're a Scrum master, which is a person who leads a small team of developers and one product owner through the process of solving a complex problem. Those best suited for roles in Scrum also appreciate and have the discipline to follow a step-by-step process to solve a problem or achieve a goal because leaving out aspects of Scrum or not following its rules limits the benefits of using Scrum. Someone who has a role in Scrum must be a team player and be skilled at working collaboratively with others to decide who does what, how it's done, and when it's done.
