The kanban card is, in effect, a message which signals depletion of product, parts, or inventory. When received, the kanban triggers replenishment of that product, part, or inventory. Consumption, therefore, drives demand for more production, and the kanban card signals demand more product — so kanban cards help create a demand-driven system.
The Feature is integrated and accepted then deployed. The "commitment point" is the "Feature Selected" column. The "delivery point" is the "Delivered" column. This board is similar to many kanban boards used in development but it is not a representation of any specific board. Specific similarities are coincidental.

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.

A kanban board. A kanban board is one of the tools that can be used to implement kanban to manage work at a personal or organizational level.. Kanban boards visually depict work at various stages of a process using cards to represent work items and columns to represent each stage of the process.
It has vertical columns for identical time intervals of production. In the illustration on the right, the time interval is thirty minutes. Production control kanban are placed in the pigeon-holes provided by the box in proportion to the number of items to be built of a given product type during a time interval.
The INVEST mnemonic for Agile software development projects was created by Bill Wake [1] as a reminder of the characteristics of a good quality Product Backlog Item (commonly written in user story format, but not required to be) or PBI for short.
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).
