As part of self-organization Scrum Teams figure cut their own WIP Limits.
WIP Limits inhibit self-organization since they limit the team's autonomy to pull work.

Your Scrum Team's cycle time is currently 8 days or less with 85% confidence. The learn has set the Service Level Expectation (SLE) accondingly. If an item in progress has just aged past your dataset's 50th percentile, what can we say about the chance it will fail to meet the team's 8-day SLE?
(choose the best answer)
We cannot predict with any level of confidence what will happen with the work item at this point.
There is now a higher chance to meet the team's SLE.
Nothing changed. We're still 85% confident the card will meet the SLE.
There is now a lower chance it will meet the team's SLE.

The Sprint is an example of a cadence.
A Scrum Team will eventually stop using Sprints if they correctly implement Kanban.

What is true about the Sprint Goal if the Development Team reserved capacity for unplanned work during an upcoming sprint?
(choose the best answer)
The Development Team should never reserve any capacity for unplanned work. It is inefficient if a Development Team's forecast does not take into account all of their capacity.
The Sprint Goal becomes more important. It can help the Development Team maintain their focus as new Product Backlog items are brought into the Sprint Backlog.
The Sprint Goal no longer helps the Development Team. They do not know what they will be working on.
