You are leading an agile project with a newly formed team. During the first two sprints, you notice that one team member, Sarah, consistently remains quiet during daily stand-ups and retrospectives. When she does speak, her contributions are valuable, but she appears uncomfortable in group settings. Other team members have started making decisions without her input. The team's velocity is acceptable, but you sense Sarah's potential is not being fully utilized. What should you do first to address this situation?

You are facilitating a sprint planning meeting for your agile team. One team member consistently volunteers to take on all the high-priority user stories, while other team members are hesitant to commit to work. This pattern has continued for several sprints, and you are concerned about team balance and knowledge sharing. What is the best approach to address this?

Your hybrid project has a distributed team across three time zones. The agile software development team conducts daily standups, while the regulatory compliance team works in traditional phases with monthly reviews. You notice that collaboration between these groups is minimal, causing delays when compliance requirements impact sprint deliverables. The compliance lead insists their work cannot be broken into smaller increments, while the development team lead complains about last-minute compliance changes. What is the best approach to improve collaboration?
