In other articles, we have talked about what Scrum is, its mechanics, and some of its roles, however, it is very important to keep in mind its definition. Scrum is a process of collaboratively performing a set of tasks regularly to fulfill a particular objective within a specific time frame.
Let’s now talk about Scrum roles, their responsibilities, skills, and the importance they play in the proper implementation of this methodology. With this clear, we will get more organization and efficiency. So, let’s start:

Scrum Master
The Scrum Master is responsible for ensuring the effectiveness of all Scrum Team roles, helping each of its members improve their practices.

This role is in charge of maximizing the product value and the work of the Scrum Team.

However, they can rely on other Scrum roles to clarify details and define criteria to help make the best decisions.
