What actions do you take if tasks are completed earlier than planned during a sprint?

If the tasks in a sprint are completed earlier than the planned deadline, I take the following actions:

• Check if there are additional tasks from the backlog that can be taken and completed within the current sprint.
• Assist colleagues with their tasks if they face difficulties or need help.
• Conduct refactoring and improvement of already completed code to enhance product quality.
• Discuss with the team and manager the possibility of adding new tasks or preparing for the next sprint.
• Use the time for learning and skill enhancement if there are no urgent tasks.

This approach helps to use time efficiently and maintain a high level of team productivity.
