Lagging indicator metrics are metrics that provide information about past performance:

1.Velocity (Option A): This is a measure of the amount of work a Scrum Team completes in a Sprint. It is a lagging indicator because it reflects what has been done rather than predicting future performance.

2.Cycle Time (Option B): This metric measures the time taken to complete a work item from start to finish. It is a lagging indicator because it provides data on how long work items took to complete in the past.

3.Throughput (Option D): This refers to the number of work items completed in a given period. Like Velocity, it reflects past performance and is considered a lagging indicator.

Work in Progress (Option C) and Work Item Aging (Option E) are not lagging indicators:

•Work in Progress (C): is a current state metric that indicates how much work is currently in progress.

•Work Item Aging (E): is a leading indicator, providing insights into how long a work item has been in progress, helping predict delays or bottlenecks

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

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

The Kanban Guide for Scrum Teams outlines four primary Kanban practices essential for Scrum Teams:

Visualization of the Workflow.

Limiting Work in Progress (WIP).

Active management of work items in progress.

Explicit policies for workflow management, often including the identification of bottlenecks​.

Inspecting and adapting the workflow is not explicitly listed as a Kanban practice for Scrum Teams. While inspection and adaptation are fundamental to Scrum (due to its reliance on empiricism), they are not specific to the set of Kanban practices integrated into Scrum​​.

Cycle Time is a lagging indicator, meaning it can only be measured after a work item is complete. Therefore, it cannot be used as a leading indicator of the length of the feedback loop (Option A). Additionally, Cycle Time is not typically used during the Daily Scrum to help Developers inspect and adapt their Sprint; rather, it is more often used to assess overall process efficiency
