Just in time in logistics: efficiency down to the second
The logistics industry has always faced the challenge of delivering goods and materials at the right time, to the right place and in the right quantity. In a world that is becoming increasingly fast-paced and interconnected, one concept has proven to be particularly efficient: just-in-time (JIT). But what exactly does this term mean, and why is it so important for modern logistics? In this new series, we explain important terms, systems and technologies from the world of logistics. Today: ‘Just-in-time’.

What does ‘just in time’ mean?
The term ‘just in time’ originally comes from the automotive industry, specifically from the Japanese car manufacturer Toyota. It refers to a production and delivery strategy in which materials and goods are delivered exactly when they are needed – not earlier and not later. Ideally, this means that no time is wasted on storage and no unnecessary storage costs are incurred. Production runs smoothly in this way, as only the necessary components are provided.
The principle of JIT in brief:
- Delivery exactly when needed
- Minimisation of stock levels
- More efficient use of resources
Why is ‘just in time’ so important for logistics?
In the modern economy, where costs and efficiency play a key role, JIT offers numerous advantages. Here are some of the main reasons why the concept is so important:
- Cost reduction
One of the biggest advantages of JIT is the reduction in storage costs. Companies do not need to keep large inventories, which not only saves space but also minimises the risk of materials becoming obsolete or damaged. This leads to a significant reduction in costs in the logistics chain.
2. Optimised resource planning
The just-in-time strategy enables companies to plan their resources better and use them more efficiently. Since only the necessary quantities of raw materials or products are delivered, production can continue without major delays and with minimal downtime. This is particularly crucial in industries with high precision and quality requirements.
3. Improved supply chain transparency
Another advantage is increased transparency in the supply chain. Suppliers and companies must work closely together to ensure that deliveries arrive on time. This creates a closer bond between the various players in the supply chain, resulting in a better flow of information and smoother processes.
4. Less waste
Just-in-time contributes to reducing waste. Since only what is actually needed is delivered, overproduction is avoided. This not only protects the environment, but also promotes more sustainable production methods.
Challenges of ‘Just in Time’
Despite all these advantages, there are also some challenges associated with the JIT principle. Since inventories are reduced to a minimum, unforeseen events such as delivery delays or production downtimes can quickly lead to bottlenecks. Natural disasters, supplier problems or logistical disruptions can bring the entire supply chain to a standstill. Heavy reliance on punctual deliveries therefore increases the risk of production downtime.
Example: Impact of the COVID-19 pandemic
The global pandemic has shown how vulnerable just-in-time supply chains can be. Many companies that relied on this system suddenly faced bottlenecks in raw materials and intermediate products as international supply chains were disrupted. This has led some companies to rethink their logistics strategies and rebuild their inventories, at least in part.
Conclusion: The future of ‘just in time’ in logistics
Despite the challenges, JIT remains an indispensable concept in modern logistics. The advantages – from cost reduction and increased efficiency to resource conservation – are enormous. However, companies must keep an eye on the potential risks and, if necessary, take measures to protect their supply chains against disruptions. A smart mix of just-in-time and contingency plans could be the key to maximising the benefits while being prepared for unexpected events.
