What skills do I need to be a good scrummaster?

Based on my experiences, my list would go like this -

Have empathy. This is the most important. Learn continuously. This is the second most important. Apart from these, you need

• Understanding of the organization and its culture
• Understanding of the team and its dynamics
• Understanding of the people on the team
• Facilitation skills
• Conflict resolution skills
• Ability to work with people
• Ability to coordinate with teams
• Ability to work with management
• Ability to solve problems and get things done

What does your list look like?
