During sprint planning, your development team commits to 45 story points based on historical velocity. However, your product owner insists they must complete 60 story points this sprint because of a commitment made to a key stakeholder. The product owner argues that the team 'just needs to work harder' and threatens to escalate to senior management if the team doesn't comply. The team looks to you, the Scrum Master, for guidance. How should you respond?

Your agile team has a new member, Sarah, who joined two weeks ago. Sarah has strong technical skills but comes from a traditional waterfall background. During the current sprint, you notice Sarah working in isolation, not updating the task board, and not asking for help despite her story being blocked. In the standup, she reports 'everything is fine' even though you can see she's struggling. Other team members have offered help, but she politely declines. What is the most effective way to help Sarah adapt to the agile team environment?

You are coaching a newly formed agile team for a financial services project. Three team members have deep expertise in the legacy systems but no agile experience, while two members are experienced agile practitioners but new to the domain. During the first sprint, you notice the legacy experts are reluctant to break work into small increments and prefer to complete entire features before showing anything. The agile practitioners are frustrated by this approach. The team is struggling to complete even simple stories. How should you address this?
