KanBan

In Japanese, the word "Kan" means "visual" and "ban" means "card," so Kanban refers to visual cards

Kanban (看板) (signboard or billboard in Japanese) is a scheduling system for lean manufacturing and just-in-time manufacturing (JIT). Taiichi Ohno, an industrial engineer at Toyota, developed Kanban to improve manufacturing efficiency.

The simplest Kanban board start with three columns – “Requested”, “In Progress” and “Done”.
