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

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.

Little's Law states:

•Average Cycle Time = Average Work in Progress (WIP) / Average Throughput.

Little's Law is used to understand and forecast the performance of a workflow system. It implies that if you know two of these three variables (Cycle Time, WIP, Throughput), you can calculate the third. The correct formula is Option A(

Options B, C, and D do not correctly state Little's Law.

Throughput, which measures the number of items completed over a specific period, is essential forforecasting future delivery rates. By analyzing historical throughput data, Scrum Teams using Kanban can make informed predictions about how many items they can complete by a given date. References: The Kanban Guide for Scrum Teams​​.
