An SLE combines a timeframe (elapsed days) and a probability, representing the likelihood that a work item will be completed within that timeframe. This helps to set realistic expectations for stakeholders and guide the team in maintaining a predictable flow. References: The Kanban Guide for Scrum Teams​.

Sprints remain a core aspect of the Scrum framework, regardless of the use of Kanban. Sprints provide a time-boxed cadence and structure that is integral to Scrum.

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
