We went with following board structure in our company.
Backlog | Next sprint | Current sprint | Done
Buffer | Working
Lanes are assigned to specific members. Each member has different job at our office so the tasks vary. We add what we have to work on to our Backlog, then move it into Next Sprint if it approaches the deadline. Blocked green tasks are used for continuous tasks that have to be worked on daily. Red cards indicate importance of the task and have to be finished as soon as possible.
Our board allows us to collaborate freely and add tasks to each others swimlanes if we need something to be done by different department.
We use KanbanTool (Kanbantool.com) to visualize our workflow and manage projects. It's really intuitive and easy to use. Our team communication has improved tremendously.
