Upon which of the five Scrum Values does Professional Scrum with Kanban build?
(choose the best three answers)
ACD
Explanation:
Professional Scrum with Kanban builds upon the core Scrum values to enhance flow and
effectiveness within the team. The relevant values are:
•
Courage: Encourages team members to address issues, experiment with changes in the
workflow, and make adjustments transparently, even when facing uncertainty.
•
Focus: Enhances the team's ability to concentrate on achieving the Sprint Goal and flow of
work items by using Work in Progress (WIP) limits and other Kanban practices.
•
Openness: Promotes an open environment where the team transparently shares information
on work progress, obstacles, and opportunities for improvement, which is key for continuous
inspection and adaptation in Kanban.
These values directly support the empirical process control and continuous improvement principles
of Kanban
True or False: The primary effect of limiting Work in Progress (WIP) is that it creates a pull
system.
A
Explanation:
The primary effect of limiting Work in Progress (WIP) is to create a pull system. A pull system ensures
that new work is only started when there is capacity, meaning that work is "pulled" into the system
when the team has the availability to do so. This approach prevents overloading the team and helps
maintain a steady and predictable flow of work, aligning with the Kanban practices within the Scrum
framework
Who must change the Work in Progress (WIP) Limits in the Definition of Workflow when urgent
work emerges from the Sprint?
(choose the best answer)
D
Explanation:
In Professional Scrum with Kanban, the Work in Progress (WIP) limits are set as a policy to maintain a
sustainable flow of work. Urgent work emerging does not automatically warrant changing these WIP
limits; instead, the team should first discuss how to accommodate the urgent work within the
existing constraints. Modifying WIP limits for urgent work could undermine the benefits of a
controlled flow, which is why urgent work should not be a reason to change WIP limits during a
Sprint
True or False: If you reduce your batch size, your overall efficiency will always increase.
B
Explanation:
Reducing batch size does not always guarantee an increase in overall efficiency. While smaller batch
sizes can lead to faster feedback, more frequent deliveries, and reduced risk, there can be situations
where reducing the batch size too much results in inefficiencies, such as increased overhead costs or
excessive context switching. Thus, the relationship between batch size and efficiency depends on the
context, system constraints, and the nature of the work
When can a Work in Progress (WIP) Limit change?
(choose the best answer)
A
Explanation:
Work in Progress (WIP) Limits can be adjusted at any time as needed to optimize flow and improve
the system's efficiency. The decision to adjust WIP limits is typically informed by the team's
observations of flow metrics (e.g., Cycle Time, Throughput, and Work Item Age) or to address
bottlenecks or inefficiencies.
Supporting Reasons:
Kanban's Flexibility:
Unlike rigid frameworks, Kanban allows for flexibility in changing WIP limits whenever necessary to
adapt to evolving conditions.
Scrum Events:
Adjustments to WIP limits are often discussed during events like the Sprint Retrospective or Daily
Scrum, but these are not the only times changes can be made.
Empirical Process Control:
Teams use transparency, inspection, and adaptation to decide when to change WIP limits based on
real-time needs.
Why Not the Other Options?
B . When the Product Owner decides to change it:
Incorrect. WIP limits are a team decision and are not controlled solely by the Product Owner.
C . It never changes:
Incorrect. WIP limits are not static; they are dynamic and evolve based on team and system needs.
D . Only during the Sprint Retrospective:
Incorrect. While the Sprint Retrospective is a common time to discuss adjustments, changes are not
restricted to this event.
E . Only during Sprint Planning:
Incorrect. Sprint Planning focuses on selecting work for the Sprint, not exclusively on adjusting WIP
limits.
F . Only during the Daily Scrum:
Incorrect. Adjustments can be made during the Daily Scrum but are not limited to this event.
Adjusting WIP limits at any time ensures the team maintains an optimal flow, a core principle of The
Kanban Guide for Scrum Teams.
A Scrum Team's Definition of Workflow must have defined points at which the Scrum Team
considers work to have started and to have finished. This allows the team to track their Work in
Progress (WIP). How are these points defined?
(choose the best answer)
B
Explanation:
The Definition of Workflow includes the agreed-upon points at which the Scrum Team considers work
to have started and finished. These points are determined based on the boundaries and scope of the
team's workflow. This definition must be clearly understood by the entire team to track Work in
Progress (WIP) effectively and manage flow efficiently. It is up to the Scrum Team to define these
boundaries to suit their specific context and workflow needs.
True or False: Work Item Age is a leading indicator for the length of the Scrum Team's
feedback loop for that (in progress) item.
A
Explanation:
Work Item Age is the amount of time a work item has been in progress. It acts as a leading indicator
for the length of the Scrum Team's feedback loop for that item. If a work item stays in progress for
too long, it indicates that feedback is delayed, potentially impacting the team's ability to adapt and
respond effectively. Tracking Work Item Age helps the team monitor flow and take timely actions to
ensure that feedback loops remain short and effective
You still need a Scrum Master when applying Kanban practices in the Scrum framework.
(choose the best answer)
C
Explanation:
You always need a Scrum Master when applying Kanban practices in the Scrum framework. The role
of the Scrum Master remains crucial, even when Kanban practices are incorporated, as they are
responsible for ensuring that the Scrum framework is followed, including all the new practices
introduced by Kanban. The Scrum Master helps facilitate the team's understanding and use of flow-
based metrics and practices while maintaining the integrity of Scrum events, roles, and artifacts
What is a probabilistic forecast intended to communicate?
(choose the best answer)
C
Explanation:
A probabilistic forecast is intended to communicate a prediction based on historical data, showing
the likelihood of completing a certain amount of work within a given time frame. It helps the team
and stakeholders understand the probability of meeting certain goals or deadlines based on past
performance, supporting more informed decision-making
True or False: The Scrum Framework contains elements that can be treated as explicit
policies.
A
Explanation:
The Scrum framework contains elements that can be treated as explicit policies. For example, Scrum
defines specific roles, events, and artifacts, which are treated as rules or guidelines that the team
must follow to maintain Scrum's framework. In the context of Scrum with Kanban, additional explicit
policies, such as Work in Progress (WIP) limits, may also be established to further optimize flow
