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).
An example of a simple kanban system implementation is a "three-bin system" for the supplied parts, where there is no in-house manufacturing. [19] One bin is on the factory floor (the initial demand point), one bin is in the factory store (the inventory control point), and one bin is at the supplier.
Production Kanban is designed for a replenishment quantity that may be smaller than a lot size or batch. It is based on a "dual card Kanban" system where a "move" card or container represents the quantity required by the downstream point of consumption and a "produce" card is kept on a display board and accumulates to a replenishment batch.
A kanban board in software development. Kanban can be used to organize many areas of an organization and can be designed accordingly. The simplest kanban board consists of three columns: "to-do", "doing" and "done", [3] though some additional detail such as WiP limits is needed to fully support the Kanban Method. [4]
An example of a Heijunka box. The Heijunka box allows easy and visual control of a smoothed production schedule. A typical heijunka box has horizontal rows for each product. It has vertical columns for identical time intervals of production. In the illustration on the right, the time interval is thirty minutes.
It is effectively an amalgam of MRP for planning, and kanban techniques for execution (across multi-echelon supply chains) which means that it has the strengths of both but also the weaknesses of both, so it remains a niche solution. The problems with MRP (as listed above) also apply to DDMRP. Additional references are included below. [10] [11 ...
[4] Some people consider a cumulative flow diagram to be a more sophisticated version of a "burn up chart", which is the opposite of a burn down chart . A burn down chart tracks work remaining over time while burn up charts like the CFD track the growth (or shrinkage) of work in certain states over time.
CONWIP is a kind of single-stage kanban system and is also a hybrid push-pull system. While kanban systems maintain tighter control of system WIP through the individual cards at each workstation, CONWIP systems are easier to implement and adjust, since only one set of system cards is used to manage system WIP.
