How does the process of task processing and movement work after its breakdown and addition to the task list before sprint start?

After a task is broken down into subtasks and added to the task list before the sprint starts, several stages of processing and moving the task occur:

1. Prioritization and estimation: The team assesses each subtask for complexity and priority to determine the order of execution.

2. Assignment of performers: Each subtask can be assigned to a specific developer or group.

3. Moving to the sprint: Subtasks from the overall list (backlog) are transferred to the active sprint — usually done in a task management system (e.g., Jira, Trello).

4. Tracking status: During the sprint, tasks are moved through statuses (e.g., "In progress", "In review", "Done"), reflecting progress.

Thus, after breakdown, the task becomes a set of specific, manageable work items that are planned and controlled within the sprint for effective execution.
