About the Kanban Board
A Kanban board is a tool to implement the Kanban method for projects. Traditionally, this tool has been a physical board, with magnets, plastic chips, or sticky notes on a whiteboard to represent work items. However, in recent years, more and more project management software tools have created online Kanban boards.
A Kanban board, whether it is physical or online, is made up of different swim lanes or columns. The simplest boards have three columns: to do, in progress, and done. The columns for a software development project may consist of backlog, ready, coding, testing, approval, and done columns.
Kanban cards (like sticky notes) represent the work and each card is placed on the board in the lane that represents the status of that work. These cards communicate status at a glance. You could also use different color cards to represent different details. For example, green cards could represent a feature and orange cards could represent a task.
