How is average lead time measured in a Kanban system?
In a Kanban system, average lead time is measured by observing the horizontal distance between the arrival and departure lines on a cumulative flow diagram (CFD). The CFD visualizes the flow of work items through various stages of the workflow. The horizontal distance between the points where work items enter and leave a particular stage represents the lead time. By calculating this distance over multiple items, teams can determine the average lead time, providing insights into process efficiency and areas for potential improvement.
Which two statements are true about a Feature? (Choose two.)
Completed by a Single Agile Release Train within one PI:
Definition: A Feature in SAFe is a service or functionality that meets the needs of a customer and can be delivered within a single Program Increment (PI) by an ART.
Prioritized using Weighted Shortest Job First (WSJF):
Definition: WSJF is a prioritization method used in SAFe to sequence work for maximum economic benefit.
SAFe Scrum Master Reference:
SAFe framework details the concept of Features, emphasizing their completion within a PI and their prioritization using WSJF to maximize value delivery.
What is one problem with phase-gate Milestones?
Phase-gate milestones are traditional project management mechanisms that mark the end of one phase and the beginning of another. One major problem with phase-gate milestones is that they assume a point solution exists and can be built correctly the first time. This assumption does not account for the iterative nature of Agile methodologies, where solutions are developed incrementally and iteratively, with feedback loops and continuous improvement. Assuming a point solution can be finalized early often leads to rigidity, lack of adaptability, and higher risks of delivering a product that does not meet the actual needs or expectations.

The work within one state of a team's Kanban board is being completed at varying times, sometimes running faster and sometimes slower than the next state. What could resolve this issue?
Creating a buffer state between two states in a Kanban board can help regulate the flow of work and address the varying completion times.
Buffer State Purpose: Acts as a holding area to balance the flow between different stages of work, smoothing out variances in completion times.
Flow Regulation: Ensures that work can continue smoothly without bottlenecks or idle times.
Work In Progress (WIP) Limits: Helps maintain a steady flow by preventing too much work from accumulating in any one state.
This approach aligns with Lean principles of managing flow and reducing variability in processes.
