PSK-I Exam Dumps - Professional Scrum with Kanban (PSK 1) Exam

Limiting Work in Progress (WIP) is likely to increase rather than reduce collaboration within a Scrum Team. When WIP limits are enforced, team members are encouraged to "swarm" around fewer tasks, focusing on completing them together rather than starting new work. This promotes more collaborative behaviors, such as pairing or mob programming, to get work items done efficiently

1.The Kanban Board Provides Transparency (Option A):

A Kanban board visualizes the flow of work, making it easy for the Scrum Team to see the status of work items, identify bottlenecks, and inspect and adapt their processes. This visual transparency is a fundamental aspect of both Scrum and Kanban and supports the empirical process control central to Scrum(

2.Kanban Helps Achieve Faster, Healthier Flow (Option D):

By focusing on optimizing flow (e.g., reducing Cycle Time and managing Work in Progress), Kanban helps Scrum Teams achieve a faster, more predictable flow of work. This improvement in flow brings more rapid transparency, allowing for more effective inspection and adaptation during Scrum events such as the Daily Scrum, Sprint Review, and Sprint Retrospective(

Option B (Kanban metrics are used in the Sprint Review to allow the Product Owner to inspect Throughput and adapt the Scrum Team's Cycle Time) is not necessarily accurate, as the Sprint Review focuses on the product increment and stakeholder feedback, not directly on Kanban metrics.

Option C (Kanban helps Scrum Teams deal with simple and complicated work where empiricism is not necessary) is incorrect because both Kanban and Scrum rely on empiricism (transparency, inspection, and adaptation) to deal with work complexity

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.

Little's Law is a formula used to understand the relationship between system throughput, work-in-progress (WIP), and lead time. While it can be used to analyze and optimize the flow of work, it is not specifically designed for forecasting a Scrum Team's output.

Scrum Teams typically use techniques like story point estimation and historical velocity to forecast their output.

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

Supplementing Scrum with Kanban practices can bring several benefits to a Scrum Team:

•Greater Collaboration (A): By using Kanban practices like visualizing work and managing flow, team members have clearer visibility into each other's tasks, fostering better collaboration.

•Reduced Average Cycle Time (C): Kanban's focus on flow and limiting WIP helps decrease the time it takes for items to move from start to finish.

•Better Transparency (D): Kanban practices enhance visibility into the current state of work, making it easier to identify bottlenecks and areas for improvement.

•Discover Areas of Variability (E): The use of flow metrics such as cycle time and throughput in Kanban can help identify variability in processes, enabling the team to make adjustments for more predictable delivery

A Service Level Expectation (SLE) in Kanban provides an agreement or expectation regarding the time it will take to complete a work item. An SLE consists of two main elements:

1.A probability (Option B): This is the likelihood or confidence level (e.g., 85%) that a work item will be completed within the specified period.

2.A period of elapsed days (Option D): This defines the maximum amount of time (e.g., 10 days) expected for a work item to be completed. The combination of these two elements helps set clear expectations and guide planning and forecasting efforts(

Options A (A cost of delay) and C (A forecasted date) are not part of the standard elements defining an SLE. The cost of delay is a concept related to prioritization, and a forecasted date is usually derived from the SLE but is not part of it.

When Developers limit Work in Progress (WIP) within a Sprint:

1.Developers Stop Beginning Work and Start Finishing Work (Option A):

Limiting WIP encourages the team to focus on completing work that has already been started rather than starting new tasks. This "stop starting, start finishing" approach helps to reduce multitasking and ensures that tasks are completed more efficiently(

2.Self-management Strengthened Due to Increased Transparency (Option C):

Limiting WIP increases transparency by clearly showing what work is in progress and what remains to be done. This heightened visibility encourages the Developers to self-manage more effectively, as they can see what needs attention and make collective decisions about the next steps(

3.Increased Collaboration/Swarming Between Developers (Option D):

With a limited amount of work in progress, Developers are more likely to collaborate or "swarm" on the tasks that are currently active. This can lead to faster completion of tasks, shared knowledge among team members, and a stronger sense of teamwork(

Option B (The amount of work done by the end of the Sprint would be reduced) is not necessarily correct. Limiting WIP does not inherently reduce the amount of work completed; instead, it aims to improve focus, reduce waste, and ensure more consistent delivery.
