Final answer:
The Scrum Team should re-prioritize tasks to focus on essential items, rather than extending the Sprint or adding more time. It's important to maintain the Sprint's fixed duration for consistency and to use the experience to improve future Sprints.
Step-by-step explanation:
If the Scrum Team finds that there are remaining tasks towards the end of a Sprint, they should not automatically extend the Sprint duration or add more time to complete the tasks. Instead, the Scrum principle suggests that the team should re-evaluate and adjust their work to make the most effective use of the remaining time. This can include re-prioritizing tasks to focus on the most essential items and potentially dropping or reassigning tasks that are deemed lower priority. It is important to maintain the time-box of the Sprint to keep a consistent rhythm and avoid setting a precedent of extending Sprints, which can lead to decreased productivity and discipline within the team. Additionally, requesting additional resources to complete tasks is generally not advisable, as the composition of the team should remain constant throughout the Sprint to ensure a stable working environment. Ultimately, the Scrum Team, including the Product Owner and Scrum Master, should discuss the issue in the Sprint Review or Retrospective to learn from the experience and improve future Sprints.
