Kanban (Japanese: 看板 meaning signboard) is a scheduling system for lean manufacturing (also called just-in-time manufacturing, abbreviated JIT). [2] Taiichi Ohno, an industrial engineer at Toyota, developed kanban to improve manufacturing efficiency. [3] The system takes its name from the cards that track production within a factory.
The technique was described by Taiichi Ohno at Toyota Motor Corporation. Others at Toyota and elsewhere have criticized the five whys technique for being too basic and having an artificially shallow depth as a root cause analysis tool (see § Criticism ).
Ohno Taiichi (大野耐一, Ōno Taiichi, February 29, 1912 – May 28, 1990) was a Japanese industrial engineer and businessman. He is considered to be the father of the Toyota Production System , which inspired Lean Manufacturing in the U.S. [ 1 ] [ 2 ] He devised the seven wastes (or muda in Japanese) as part of this system.
The diagram here shows a software development workflow on a kanban board. [4]Kanban boards, designed for the context in which they are used, vary considerably and may show work item types ("features" and "user stories" here), columns delineating workflow activities, explicit policies, and swimlanes (rows crossing several columns, used for grouping user stories by feature here).
Toyoda collaborated with Taiichi Ohno, a veteran loom machinist, to develop core concepts of what later became known as the 'Toyota Production System', such as the Kanban system of labeling parts used on assembly lines, which was an early precursor to bar codes. [5]

Taiichi Ohno, "father" of the Toyota Production System, originally identified seven forms of muda or waste: [6] Seven types of waste identified in lean manufacturing A mnemonic may be useful for remembering the categories of waste, such as TIM WOOD or TIM WOODS (with the S referring to Skills).
While virtually all major improvement paradigms in use in the West incorporate some element of visuality, the entire codified set of visual principles and practices, from the foundation of 5S through to visual guarantees (poka-yoke), rests on this definition: "The visual workplace is a self-ordering, self-explaining, self-regulating, and self ...
