In Kanban, how can we break down work? Lets say we have a task of setting up a new server. To do so it requires some investigation, a purchase, physical mounting, configuring the software etc.
When placing this task in a Kanban, how do we handle the sub-tasks of the main task? Should we divide the big task into many small tasks and drag those through the system or should we just keep the big one (with no subtasks) and drag that through the system?
