What is the Pull system?
It is one where work is only initiated when there is demand for it.
Definition
In Kanban, a Pull system is one where work is only initiated when there is demand for it, as opposed to a Push system that relies on forecasts and can lead to overproduction.
Just-in-Time
Pull systems are integral to the Just-in-Time (JIT) production model, where goods are produced to meet actual demand, reducing excess inventory and waste.
Kanban Signals
Kanban uses visual signals, such as cards and wip limits, to indicate when work should be started, linking production directly to customer demand.
Waste Reduction
Pull systems help minimize waste by aligning production with actual demand, leading to more efficient use of resources.
