Time-Boxing

5 minutes 5 Questions

Time-Boxing is a fundamental concept in Scrum that refers to limiting the amount of time allowed for an event or process to occur. Each event (or ceremony) in Scrum (like Sprint Planning, Daily Standup, Sprint Review, and Sprint Retrospective) is time-boxed to ensure it does not exceed a fixed duration, allowing the team to stay focused, thus providing a continuous and predictable rhythm. It also helps to prevent process-related work from overtaking actual product development. Time-Boxing forces decisions, thus promoting progress.

Time-boxing is an important concept in Scrum that helps to manage the progress of tasks. It involves allocating a fixed, maximum unit of time for an activity.

Why is it important?
It helps to ensure that the team stays on schedule and that tasks are completed within a determined time frame, promoting efficiency. It also ensures that time and resources are not expended disproportionately.
What is it?
It is a time management technique where a time limit is assigned to a task. In Scrum ceremonies, each event has a specified duration that is not extended.
How it works?
Once a time-box period begins, it continues until the period ends or the purpose of the time-box is achieved. At the end, work is evaluated.

Question 1

The team had a productive sprint, completing several tasks ahead of time. Which is the best way to adjust timeboxing?

Increase the duration of the timeboxes Give the team a longer break End the sprint early Pretend no changes occurred Add new tasks to future sprints Review the remaining tasks and plan additional work

Correct Answer: Review the remaining tasks and plan additional work

If the team finished tasks ahead of time, it's best to review the remaining tasks and plan some additional work that could be done. Other options either waste potential productivity or lead to inefficiencies.

Question 2

While timeboxing, the team realizes that lower priority tasks are often left unresolved. What should they do in this case?

Remove all lower priority tasks from the project Revisit priorities and allocate appropriate time for each task Ignore the unfinished tasks Assign lower priority tasks to less skilled team members Limit the number of higher priority tasks Work overtime to finish the lower priority tasks

Correct Answer: Revisit priorities and allocate appropriate time for each task

Revisiting and adjusting priorities ensures that all tasks are taken care of within the available timeboxes. Other options may lead to reduced quality, team burnout, or incomplete projects.

Question 3

A timeboxed activity is taking longer than expected. What should the team do?

Keep working on the activity indefinitely Evaluate the situation, adjust the timebox, and communicate changes Subtract the extra time from the next timebox Ignore the exceeding time Ask for more resources Cancel the activity altogether

Correct Answer: Evaluate the situation, adjust the timebox, and communicate changes

When a timeboxed activity takes longer than expected, it's important to evaluate the situation, adjust the timebox, and communicate the changes to maintain project control. The other options may lead to further delays.
