Kanban & Just in Time (JIT)

Published on 21 January 2020

What are Push and Pull Systems, Kanban and Just In Time (JIT) – and how will they help my workplace?

Push Systems describes a traditional manufacturing process where the factory makes product before the next process or customer is ready for it. The product is pushed onto the next process or into the market, as opposed to being made to order. Lean encourages pull systems through Kanban control, with Just In Time (JIT) being a perfect goal to strive towards.

Push systems come from the view that machines and processes should always be kept as busy as possible, as a priority over the actual volume demanded by the customer. The downside to this approach is excessive inventory and Work in Progress (WIP).

Pull systems provide the ability to respond to customer demand by taking a signal, a Kanban, from an upstream process to produce. If no signal is received, i.e. no product is required, then nothing is produced.

There are several advantages of reduced inventory and WIP including reduced clutter and transport, freed up cash and short lead times.

JIT is the ultimate evolution in inventory control. A JIT system contains a minimal level of inventory until the next shipment of material arrives “just in time” or just before it is required. This concept was perfected by Toyota, who recognised the cost of keeping inventory, but also recognised that inventory forms an important function of smoothing out variation in demand, to avoid the cost of stock shortages.
