What is a key responsibility of the Scrum Team as a whole?

A key responsibility of the Scrum Team as a whole is to ensure the delivery of a functional product increment. This is fundamental to the Scrum framework. Each iteration, or Sprint, aims to produce a product increment that meets the definition of "Done" as defined by the team. By focusing on delivering working, usable features, the team facilitates continuous improvement and value delivery to stakeholders, aligning with the Agile principle of delivering functional software frequently.

While other options may seem relevant to Scrum practices, they do not capture the core responsibility of the entire Scrum Team as effectively as ensuring a functional product increment does. Adhering strictly to the Scrum Guide is important for framework integrity but should not overshadow the primary purpose of creating value through product increments. Likewise, conducting stakeholder analysis and controlling the Product Backlog are activities that contribute to overall team success but are more specific tasks rather than overarching team responsibilities.
