Time-boxed duration

5 minutes 5 Questions

The Daily Scrum Meeting is strictly time-boxed to 15 minutes regardless of the size of the team. This ensures that the meeting remains focused and effective. If a discussion arises that requires more time, it should be set aside and addressed outside of the Daily Scrum. This respect for the meeting…

Guide: Understanding Time-boxed Duration in Daily Scrum Practices

Time-boxed duration is a fundamental principle in Scrum methodologies, including daily scrum practices.

What is Time-boxed Duration?
This refers to the practice of assigning a fixed, maximum unit of time for an activity. In Scrum, most activities are time-boxed, which means they have a set duration that cannot be exceeded. The daily scrum, for example, is time-boxed to 15 minutes.

Why is Time-boxed Duration important?
The time-boxed principle aims to minimize waste and improve efficiency. It sets a limit to keep the team focused and encourages prompt decision-making. Without this, meetings could drag on and devolve into aimless discussions.

How does it work?
When an activity is time-boxed, it must start and end within the defined time frame. If it is a meeting, all necessary points must be discussed within that fixed period. If it's a task, it must be completed within the set duration.

Exam Tips: Answering Questions on Time-boxed duration
In exams, understanding the purpose and effect of time-boxing in Scrum is crucial. Remember: Time-boxing is about managing time efficiency, not about rushing tasks. When answering questions, focus on its role in ensuring focus, limiting non-productive time, and encouraging efficient work. Also, keep in mind the actual time limits in Scrum – for instance, the daily scrum should never exceed 15 minutes. An exam might test your understanding by asking what happens when these limits are exceeded. Your answer should demonstrate your understanding of the role of the Scrum Master in enforcing time-box limits and the team's ability to self-organize under these constraints.

PSM I - Time-boxed duration Example Questions

Test your knowledge of Time-boxed duration

Question 1

During a sprint review, the Scrum Team realizes they're spending more than the allotted time box on certain tasks. What is the best course of action?

Encourage team members to work overtime to ensure tasks are completed Increase the sprint duration to accommodate more time for tasks Inspect and adapt the process to optimize for time-efficiency Introduce additional roles to the team specifically to manage time allocation

Correct Answer: Inspect and adapt the process to optimize for time-efficiency

In Scrum, when a team realizes they're spending more time than expected on tasks during a sprint review, the best course of action is to inspect and adapt their processes. This means analyzing why the tasks are taking longer than predicted and making necessary adjustments to improve time efficiency in the future. Increasing the sprint duration, encouraging overtime, or adding more roles are not in line with Scrum principles which emphasize sustainable work pace, cross-functionality, and self-organization without overcomplicating team structures.

Question 2

As a Scrum Master, in a four-week sprint, you realize there's a national holiday in the third week and most of the team members will be on leave. This will affect the time-boxed duration. What should you do?

Instruct the team to increase their daily working hours before and after the holiday to make up for the lost time. Adjust the Sprint Backlog to reflect the reduced capacity during the sprint planning, ensuring commitment remains realistic. Continue the sprint as planned but use the holiday to conduct in-depth code reviews and documentation updates, assuming minimal coding will be done. Automatically decrease the story points for all backlog items by a percentage equivalent to the time lost due to the holiday.

Correct Answer: Adjust the Sprint Backlog to reflect the reduced capacity during the sprint planning, ensuring commitment remains realistic.

In Scrum, it is essential to plan Sprints based on the team's capacity. Adjusting the Sprint Backlog to reflect the actual capacity during the planning phase maintains transparency and realism, ensuring that the team can still meet their commitments without overburdening themselves. Increasing daily hours is not sustainable and can lead to burnout. Reducing story points without a team discussion undermines the estimating process and fails to reflect the team's true capacity. Lastly, assuming the holiday can be used for other work does not respect the purpose of the time off and can disrupt the team's work-life balance.

Question 3

The team consistently finishes all sprint tasks before the end of the two-week time box. What should the Scrum Master suggest?

Adjust the sprint length to accommodate more work, ensuring a full utilization of the time box Encourage the team to discuss if the sprint goal was ambitious enough and if more complex items can be included in the next sprint Recommend the Development Team to use the remaining time for individual skill development, unrelated to the sprint goal Suggest the team to divide tasks into smaller ones to fill the sprint duration more accurately

Correct Answer: Encourage the team to discuss if the sprint goal was ambitious enough and if more complex items can be included in the next sprint

The Scrum Master should facilitate the team in inspecting their work and adapting their sprint backlog for future sprints if consistently finishing early. Adding slightly more work or adjusting sprint lengths does not address the underlying issue of potentially underestimating capacity or not challenging the team enough. Dividing tasks into smaller ones could lead to inefficient task management and does not ensure that the team is working on the most valuable items. Encouraging individual skill development, while beneficial in general, distracts from the sprint goal and does not leverage the team's ability to accomplish more as a unit.
