During iteration planning, the determining factor for decomposing an epic is its size and priority. Larger epics are often broken down into smaller, manageable stories to be worked on in iterations. Prioritizing helps in determining which parts of the epic need immediate attention and which can be deferred or handled later.

In Scrum, the team is self-organizing and collectively responsible for the work, including overcoming obstacles. When a team member falls behind, the Scrum Master should facilitate communication and leverage the collective intelligence of the team to find a solution. Asking the team for suggestions fosters collaboration, transparency, and ensures that the entire team is involved in addressing any issues, which is consistent with Scrum principles.

Kaizen is a Japanese term meaning continuous improvement. In the context of a newly formed scrum team that uses a Kanban board to track and resolve impediments, the emphasis on issue resolution and future prevention aligns well with the principles of Kaizen. Over time, this approach fosters a culture of continuous improvement as the team makes small, incremental changes to enhance their processes and practices.

In an agile team, it is crucial to encourage open communication and ensure that all members feel valued and supported. By assuring the new member that their inputs on impediments are valued and demonstrating this in the next meeting, the agile project leader can help build trust and confidence. This approach aligns with the principles of agile methodologies, which emphasize collaboration, transparency, and respect within the team. Addressing the new member's concerns in a team setting rather than privately also promotes a culture of open communication and inclusion, which is essential for team cohesion and productivity.

The scrum master should create a collaborative team environment so that the team can explore a solution together. Scrum emphasizes teamwork and collective problem-solving. By fostering a collaborative atmosphere, the team can leverage their combined skills and knowledge to address the technical problem, aligning with Agile principles.
