As the chapter headline suggests, Chapter 4 of Practical Kanban is all about forecasting when work is done. You will find answers to these main questions:

• When is this work item finished?
• When are these N work items finished?
• How many work items can be delivered by the date X?

The good news is that these questions are answered without estimation. In a good working system, you do not have to estimate – you know when work is done 😉 Read Chapter 4 of Practical Kanban – From Team Focus to Generating Value to learn how to do it.
