A Kanban lane is a workflow line consisting of sub-states (sub-queues) each with its own done criteria and each serving as the input queue for the next state.
By default, it comes preconfigured with three substates i.e., “To Do,” “Progress” and “Done.” The user can however configure each lane independently to contain more sub-states and in any particular order from the lane’s context menu.
Planned Lead Time of a Kanban lane sets the estimated number of days it will take from when an item is put in the kanban lane until it is Done. This number will be used to derive the planning period for planned items. Read more here.
Part of the configuration includes setting a WIP limit, max number of items, per sub-state. This WIP limit will then be shown on the Kanban lane card in brackets along with the number of Items currently in the sub-state. If the current number of items in the sub-state exceeds the WIP limit, the WIP limit will turn red. See the screen dump below:
Tasks can be created directly in a Story’s lane, using the
