Kanban is the process by which workers start to work on and finish projects, and it is often used in conjunction with lean manufacturing. The focus of lean is to get waste out of the supply chain, and the main principal behind Kanban is to move projects, or stories, through the various stages of development. Use a Kanban Station to keep track of the stories going on in your facility. This lean technique helps your facility become more productive because it also emphasizes the importance of validation. The idea is that it's just as important to validate your final product as it is to actually finish.
