What is Kanban?
Kanban allows you to work on backlog items and tasks without using sprints. It's like working in a Scrum task board, but without the sprints:
You can simply drag backlog items directly into a Kanban board and start working on them, without assigning them to a sprint first.
Kanban is useful when your work is an ongoing flow that cannot naturally be divided into sprints. It's also useful if you simply prefer to just keep working from the top of your backlog, without having to divide your work into sprints.
