Question 1

What qualitative information can you get from a Cycle Time Scatterplot? (choose the best answer)

Accepted Answer

D

Explanation: A Cycle Time Scatterplot is a visualization tool used to display the cycle times for individual work items over time. This scatterplot provides several types of qualitative information: 1. General Cycle Time Trends (Option A): The scatterplot can show general trends over time, such as whether the cycle times are decreasing, increasing, or staying stable. This helps teams understand the overall direction in which their workflow efficiency is moving. 2. Single Cycle Time Outliers (Option B): The scatterplot also helps identify individual outliers — work items that took significantly longer or shorter than usual to complete. These outliers can be further investigated to understand why they occurred and to prevent similar situations in the future. 3. Clusters of Cycle Time Outliers (Option C): In addition to single outliers, the scatterplot may reveal clusters of outliers. These clusters can indicate systemic issues, such as bottlenecks or recurring problems in a specific part of the process. Since a Cycle Time Scatterplot provides all these types of information (general trends, single outliers, and clusters of outliers), the correct answer is D.

Question 2

Scrum Teams using Kanban can start to increase predictability by: (choose the best answer)

Accepted Answer

D

Explanation: Scrum Teams using Kanban can start to increase predictability by reducing the amount of work in progress (WIP) through WIP limits. This approach helps to limit the number of items being worked on at any given time, thus reducing multitasking and context switching. It allows the team to focus on completing a few items before starting new ones, which directly impacts the flow of work and helps to predict when items will be completed. By controlling the WIP, teams can achieve a steady flow of work, improve cycle times, and make more reliable forecasts about future deliveries

Question 3

What might a Scrum Team visualize with Kanban? (choose the best three answers)

Accepted Answer

Explanation: When a Scrum Team uses Kanban, they can visualize: • The Product Backlog: By making the Product Backlog visible, the team can track what work items are upcoming and prioritize them effectively. • The Sprint Backlog: Visualizing the Sprint Backlog helps the team see the work planned for the current Sprint, track progress, and manage flow. • The Definition of Done: Making the Definition of Done visible ensures that all team members and stakeholders understand the criteria that must be met for work to be considered complete

Question 4

What is a probabilistic forecast intended to communicate? (choose the best answer)

Accepted 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

Question 5

In which of these situations should the Scrum Team adjust their Work in Progress (WIP) Limits?

Accepted Answer

A

Explanation: Adjusting WIP limits can directly impact Cycle Time and overall flow by reducing bottlenecks and increasing focus. Lowering WIP can enhance the team’s ability to complete work within a Sprint by minimizing task switching and promoting faster delivery of value. Reference: The Kanban Guide for Scrum Teams​​.

Question 6

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)

Accepted 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

Question 7

What is the best use for the Work Item Aging metric? (Choose the best two answers)

Accepted Answer

Explanation: Work Item Aging is an essential metric that helps the Scrum Team monitor progress and detect potential delays early. It is especially useful in Daily Scrums to identify items that are taking longer than expected, allowing the team to take corrective actions and prevent delays. It also serves as a leading indicator of how long the feedback loop for a Work Item may take.

Question 8

In the context of Scrum, which of the following statements about Cycle Time are true? (Choose the best two answers)

Accepted Answer

Explanation: Cycle Time measures the time taken to complete individual work items, and while some items might take longer than a Sprint, on average, teams aim to have Cycle Times shorter than the Sprint duration to ensure a smooth flow and regular delivery of value. Reference: The Kanban Guide for Scrum Teams​​.

Question 9

True or False: If Scrum is used with Kanban then having a Scrum Master is optional.

Accepted Answer

B

Explanation: Kanban does not eliminate the need for a Scrum Master when used with Scrum. The Scrum Master remains an essential role to facilitate the Scrum framework, help the team adopt both Scrum and Kanban practices effectively, and ensure the team understands and adheres to Scrum principles. The role of the Scrum Master includes coaching the team on both Scrum and Kanban practices, removing impediments, and promoting continuous improvement. Therefore, even when Scrum is used with Kanban, the Scrum Master is not optional but a critical role in ensuring that the integration of these practices is successful(

Question 10

True or False: Little's Law is used to forecast a Scrum Team's output.

Accepted Answer

B

Explanation: Little's Law establishes a relationship between three flow metrics: Work in Progress (WIP), Cycle Time, and Throughput. It provides insights into how changes in one metric affect the others in a stable system​​. Little's Law is used to understand and manage flow within a system but is not a forecasting tool for output or future performance. It assumes a stable and predictable system where the input and output rates are consistent. Why Not True? Forecasting requires variability, historical data, and often different statistical models. While Little's Law supports system predictability and capacity planning, it does not directly project future Scrum Team outputs or delivery dates​. Thus, Little's Law helps teams analyze and optimize flow but is not used for forecasting.

Question 11

True or False: A Scrum Team using Kanban does not need to craft a Sprint Goal during Sprint Planning. They can instead create one “on-demand” as new work flows into the Sprint Backlog.

Accepted Answer

B

Explanation: Even when using Kanban, Scrum Teams still follow the Scrum framework, which mandates crafting a Sprint Goal during Sprint Planning. The Sprint Goal provides focus and alignment for the team, ensuring that all work contributes toward a common objective, rather than being taken on as needed. Reference: The Scrum Guide​.

Question 12

True or False: The primary effect of limiting Work in Progress (WIP) is that it creates a pull system.

Accepted Answer

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

Question 13

True or False: If you reduce your batch size, your overall efficiency will always increase.

Accepted Answer

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

Question 14

True or False: The Scrum framework already contains elements that create a pull system.

Accepted Answer

A

Explanation: The Scrum framework already contains elements that create a pull system. In Scrum, the team members "pull" work into the Sprint Backlog during Sprint Planning. They decide which Product Backlog items they will commit to completing based on their capacity and the Sprint Goal. This is a form of a pull system where the team only takes in as much work as they believe they can complete within a Sprint, aligning with Kanban principles that limit Work in Progress (WIP) to optimize flow

Question 15

True or False: When the Developers add Kanban to Scrum, the way they use the Sprint Goal during their Daily Scrum changes.

Accepted Answer

A

Explanation: When Developers add Kanban to Scrum, the way they use the Sprint Goal during their Daily Scrum can change. In traditional Scrum, the Sprint Goal is a shared commitment for the Sprint. However, in Professional Scrum with Kanban, the focus shifts to the flow of work and delivering value incrementally. While the Sprint Goal still provides direction, the Daily Scrum may involve discussions about: Progress towards the Sprint Goal: How are we progressing towards the overall goal? Work in Progress (WIP): Are we adhering to WIP limits? Blockers and impediments: What is preventing the team from progressing? Prioritization: Are we working on the highest-value items? By focusing on these aspects, the team can ensure that they are delivering value continuously and efficiently. Thank you for your visit.
