In Agile, what signifies that a team member’s responsibilities are increasing?

The choice indicating that a team member’s responsibilities are increasing is reflected in the growth of the product backlog size. When the product backlog expands, it often means that there are more items to be developed or refined, which can require additional effort and focus from team members. This increase can lead to team members taking on more tasks, leading to a broader scope of responsibility as they work to manage and deliver on these new items.

The increase in backlog size suggests a greater demand for development work, prompting team members to collaborate more closely, adapt their skills, and potentially take on new roles to ensure timely delivery. This aligns closely with Agile principles, where the team is expected to be flexible and take ownership of the work items in the backlog.

In contrast, the introduction of new team members tends to distribute responsibilities rather than increase a single member's responsibilities. An increase in complex projects may impact the workload but does not directly signify a rise in individual responsibilities unless it is associated with the backlog. Lastly, while the demand for cross-functional skills can lead to an increase in responsibilities, it is not as directly tied to an observable increase in workload as the growth of the product backlog.
