Kanban Service Level Expectations and how to use them in Scrum
One of the new concepts we introduce in the Kanban Guide for Scrum Teams is the Service Level Expectation, defined as:
An SLE forecasts how long it should take a given item to flow from start to finish within your workflow. The SLE itself has two parts: a period of elapsed days and a probability associated with that period (e.g., “85% of work items will be finished in 8 days or less” which can also be stated as “8 days with 85% confidence/probability”).
