PSK / Forecasting
I am reading the book Practical Kanban to prepare for PSK and I have a question: there is a huge part of the book regarding Forecasting. Honestly - sometimes it even controversies with Scrum. So my question is: will there be at PSK question regarding Kanban forecasting principles or not? In my mind, there should not, because it is not related to Scrum.
Sorry if this question violates any of scrum.org rule. Many thanks in advance!
I don't remember whether I encountered a question specifically about forecasting, but it is important to consider how forecasting may be affected.
The Kanban Guide for Scrum Teams does not invalidate anything in the Scrum Guide. But teams that also use Kanban, may find that their existing processes no longer work for them. Within the Scrum Framework, they may find different ways of working.
It could be, for example, that a Scrum Team optimizes its flow so effectively, that empirical forecasts can be made about the number of items that will be Done within a Sprint.
It may be that the Development Team does not know at the start of a Sprint, what work it will pick up that doesn't relate to the Sprint Goal. It could be that their forecast is a combination of specific items they believe they will need to complete, and the number of currently unknown Product Backlog Items they expect to be able to complete during the Sprint.
Forecast is very important for agile development. The difference is to refer to what metrics and forecast what.
The Development Team forecasts the workload for the future in the Sprint planning. The Product Owner also forecasts the release time based on the progress that the development team has completed.

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 eight days or less").
