Final answer:
The roles that support the Scrum Master in removing impediments are the Product Owner, who helps by defining product backlog and prioritizing tasks, and the Development Team, who communicates about technical obstacles.
Step-by-step explanation:
To address the question: Pick roles that support the Scrum Master in removing impediments, it's important to understand that in the Scrum framework, the Scrum Master is responsible for ensuring that the Scrum Team follows the practices and rules of Scrum, and this includes removing any impediments that might slow down or block the team's progress. The Product Owner and the Development Team are two roles that actively support the Scrum Master in this duty.
The Product Owner works closely with the Scrum Master by clearly defining the product backlog items and prioritizing them based on the business value, which helps in identifying and removing impediments related to the scope or understanding of work. In contrast, the Development Team supports by communicating openly about the technical or operational obstacles they encounter, enabling the Scrum Master to address these issues promptly.
