Final answer:
An effective Scrum Master facilitates PI Planning and acts as a servant leader, always ready to support the team and the organization with flexibility, resourcefulness, and accountability.
Step-by-step explanation:
Two behaviors of an effective Scrum Master are facilitating the PI Planning session and acting as a servant leader to exhibit Lean-Agile Leadership. An effective Scrum Master should always remain willing to go above and beyond when possible and be flexible in the face of changing priorities and assignments. A servant leader focuses on the growth and well-being of people and the communities to which they belong. This leader should convey their interest in the organization's mission, respond professionally to feedback, and offer feasible solutions to problems. They actively participate, seeking ways to contribute to areas that are a priority for the manager, demonstrating resourcefulness by reaching out to team members when needed, and exhibiting accountability for any mistakes or errors in judgment.
