Which of the following terms best describes a group of tasks or items prioritized for a future sprint?

The term that best describes a group of tasks or items prioritized for a future sprint is "backlog." In the context of Agile and Scrum methodologies, the backlog serves as a dynamic list of work items that the team has identified as necessary to complete. This list is prioritized to ensure that the most important tasks are addressed first, guiding the team's focus during upcoming sprints.

The backlog is continuously refined, allowing for adjustments based on feedback, changes in priorities, or new insights, making it a critical tool for Agile project management. It helps teams keep track of what needs to be done and serves as a single source of truth regarding the work that awaits them.

The other options provided do not align with this specific context. “Inventory” typically refers to stored goods or items within a supply chain context, “agenda” generally pertains to a list of items to be discussed in a meeting, and “pipeline” is often used to describe a sequence of processes through which data or tasks flow but doesn’t directly relate to prioritized tasks for future sprints. Therefore, in Agile practices, "backlog" is indeed the most accurate term for a collection of tasks slated for execution in future iterations.
