Abstract: Whenever we talk about any product development or manufacturing process then it becomes very important that the process be perfect and premature, every process needs to be flexible. In todays era, agile is one of the ways. "Kanban" is a similar method that not only makes the production process flexible but also gives the best results through continuous monitoring. Although both Agile and kanban processes are used in the software industry, kanban is being used extensively in the field of mechanics. Kanban is not an entirely new way, but it is a means to further improve an already running process incrementally. In this article, the authors have mentioned about the history, experiments, and benefits of kanban.
