The use of Kanbans work best with pull systems for determining the timing of which products or services are produced.

The statement is correct. Kanban is a scheduling and signaling system that is a fundamental component of a pull-based production environment. In a pull system, production is not based on forecasts but is triggered by actual demand from a downstream process. The Kanban (which can be a physical card, an empty bin, or an electronic signal) serves as the authorization for an upstream process to produce or move a specific item. This mechanism ensures that work is "pulled" through the system only as needed, directly linking production timing to consumption. This prevents overproduction, a core waste identified in Lean methodologies, making Kanban an ideal tool for implementing pull systems.

B. False: This is incorrect. Kanban is not just compatible with pull systems; it is the primary mechanism used to implement and manage them. The core function of a Kanban signal is to authorize production in response to demand, which is the definition of a pull system.

In Chapter 2, Ohno describes Kanban as the "autonomic nerve" of the production line, enabling the Just-In-Time (JIT) and pull system by communicating what is needed, when it is needed, and in what amount.

International Journal of Production Research, 15(6), 553-564. The paper's abstract and Section 3 (p. 556) detail how the Kanban system is the operational tool used to achieve Just-In-Time production, which is inherently a pull system.
