JIT or illegit?

With the bounce-back from the pandemic, many countries have experienced supply-chain problems. For example, the shortage of lorry drivers in the UK and elsewhere (see the blog Why is there a driver shortage in the UK?) has led to empty shelves, fuel shortages and rising prices. The problem has been exacerbated by a lack of stock holding. Holding minimum stocks has been part of the modern system of ‘just-in-time’ (JIT) supply-chain management.

JIT involves involves highly integrated and sophisticated supply chains. Goods are delivered to factories, warehouses and shops as they are needed – just in time. Provided firms can be sure that they will get their deliveries on time, they can hold minimum stocks. This enables them to cut down on warehousing and its associated costs. The just-in-time approach to supply-chain management was developed in the 1950s in Japan and since the 1980s has been increasingly adopted around the world, helped more recently by sophisticated ordering and tracking software.

If supply chains become unreliable, however, JIT can lead to serious disruptions. A hold-up in one part of the chain will have a ripple effect along the whole chain because there is little or no slack in the system. When the large container ship, the Ever Given, en route from Malaysia to Felixtowe, was wedged in the Suez canal for six days in March this year, the blockage caused shipping to be backed up. By day six, 367 container ships were waiting to transit the canal. The disruption to supply cost some £730m.

JIT works well when sources of supply and logistics are reliable and when demand is predictable. The pandemic is causing many logistics and warehousing managers to consider building a degree of slack into their systems. This might involve companies having alternative suppliers they can call on, building in more spare capacity and having their own fleet of lorries or warehousing facilities that can be hired out when not needed but can be relied on at times of high demand.

When the ‘bounce back’ subsides, so may the current supply chain bottlenecks. But the rethinking that has been generated by the current problems may see new patterns emerge that make supply chains more flexible without becoming more expensive.

A changing supply chain

With globalisation, more and more businesses have found it beneficial to ‘go global’. There are many reasons why a firm might choose to expand its production or market to other countries and one particular advantage is cutting costs in the manufacturing of products.

Countries such as China and India have become leaders in production. Look at many of the items you own – I’m sure you’ll see a ‘Made in China’ or ‘Made in India’ amongst them. These fast emerging countries were highly sought after as places to produce due to much cheaper production costs. This advantage led to Western companies outsourcing much of their manufacturing base to China, as a means of retaining a competitive advantage.

However, the cost advantages that China boasted are now less significant and we may be about to see the emergence of a new manufacturing hub. Other countries that are further behind the BRICS in the development process now have cost advantages over places like China and so we may see another transfer of manufacturing to other parts of the world.

When splitting up a supply chain to gain cost advantages a key consideration is the extent to which you lose control. Communication and co-ordination issues can emerge when design takes place in one country; production in another and then the products are sold around the world. When cost differences are huge, these problems can be overlooked, as what they might cost you in terms of lost time etc. is easily made up by savings through cheaper labour.

However, when the cost advantages of production in China shrink, companies are still left with the problems of communication and co-ordination. These now represent more significant costs that could be reduced were production to revert to the country of design or if production were to be moved to an even cheaper country.
