The first thing that every business needs to learn is that lean manufacturing matters A LOT in supply chain management. Why? Because it ultimately plays a leading role in the business’s success.
Well, if that’s valid, here comes the question: What does effective lean manufacturing in supply chain management look like?
The answer is simple: OPTIMIZED PROCESSES, LESS WASTE Including WASTED TIME, SHORTER LEAD TIMES, ENHANCING PRODUCTIVITY, and IMPROVED CUSTOMER SERVICE.
In today’s fast-paced, competitive market, businesses are under constant pressure to deliver high-quality products at lower costs without compromising on quality in the current business landscape.
Since the supply chain is a significant part of the whole system, incorporating lean management principles at this stage becomes crucial.
These principles help businesses streamline operations from raw material to final product delivery.
Lean supply chain management is, in fact, more about creating a system that can quickly respond to market demands while having the following:
| Reduced Costs | Maximized Value | Reduced Inefficiencies |
Fortunately, businesses have examples like Amazon, Intel, and Toyota, who, by following lean principles, have won massively in their respective fields.
So, if you as a business aim to achieve such growth, here’s a guide.
Let’s uncover it and learn what makes an effective lean supply chain and what lean manufacturers should expect from their vendors.
What is the Lean Approach to Supply Chain Management?
Pioneered by Toyota in the mid-20th century, Lean manufacturing focuses on eliminating waste while maintaining high-quality production. The core lean principles, Flow, and Continuous Improvement significantly impact supply chain management when lean practices are implemented to ensure a great supply chain.
Process Flow ensures a smooth, uninterrupted movement of information, resources, and goods. Whereas continuous improvement refers to the steps and strategies implemented to ensure improvement doesn’t happen to be a one-time outcome, Waste reduction is also a core element that identifies and eliminates inefficiencies that do not add value to the supply chain.
The Pillars of a Lean Supply Chain – Learning the Basics
A successful lean supply chain operates on four key pillars. These work in coordination, side by side, to ensure smooth and efficient operations.
1. Integration
A well-integrated supply chain ensures that all stakeholders – suppliers, manufacturers, and distributors are well-coordinated and share real-time data. One of the biggest significance of staying aligned within the departments and external stakeholders is reduced miscommunication. Besides, a seamless flow of information between all supply chain points is also ensured. Also, the real-time data ensures better decision-making.
Example:
One of the classic examples of integration in managing supply chains is Amazon. The company integrates data from warehouses, suppliers, and delivery services. It then uses this data to predict demand and optimize inventory management and product re-stocking, resulting in no excess stock and improved delivery times.
2. Operations
Operations cover day-to-day activities that result in workflow optimization. It, therefore, involves scheduling, planning, and equipment maintenance to ensure uninterrupted supply chain function. The core, lean operations focus on workflow efficiency, inventory management, quality control, and continuous process improvement to eliminate waste and reduce lead times.
This can be achieved by practicing Lean methodologies and implementing various tools like JITProduction, Kaizen, Total Quality Management, Pull System, and Supplier Integration.
Example:
Intel implemented lean manufacturing principles to reduce the time it takes to bring a new microchip from production to market from 3 months to under ten days. Similarly, Nike applies lean principles in production to ensure flexible and responsive manufacturing. This efficiency can be seen in terms of Nike’s reduced waste and its adaptability to changes in demand and customer preferences.
3. Purchasing and Procurement
Sourcing high-quality materials at the best price is a crucial milestone of a lean supply chain. In-time supply can save businesses from stress and hassle besides improving profitability. To ensure this, companies have to put in the effort, for example, to strengthen relationships with suppliers to secure reliable and cost-effective inputs.
Example:
One example representing the company’s focus on purchase and procurement is Toyota. The automotive giant ensures that raw materials arrive exactly when needed, reducing storage costs and preventing overproduction.
4. Distribution and Logistics
Distribution and Logistics cover transportation, warehousing, and final product delivery to the customers. Efficient transportation and delivery ensure that products reach customers quickly and in optimal condition.
Applying lean principles to this part of the supply chain can be done by managing inventory levels, optimizing logistics, and choosing the best distribution routes.
Example:
Procter & Gamble by reducing order variability, Procter & Gamble improved its supply chain efficiency, leading to a 50% reduction in lead time. Another example that shows the impact of distribution and logistics on overall efficiency is Sony. The company faced major disruptions when the Suez Canal was blocked, delaying PlayStation shipments.
This also hints towards the importance of contingency planning in lean logistics.
The Classic, Real-Life Example: Toyota’s Lean Supply Chain
The Toyota Production System, one of the most efficient and competitive manufacturers in the world, represents a prime example of successful lean supply chain implementation. With effective lean implementation, Toyota successfully met the following parameters.
| Reduce inventory costs by producing only what is needed when it is needed. | Eliminate waste across the supply chain, optimizing resource use. |
| Increase productivity and flexibility by responding swiftly to market demands. | Enhance product quality through rigorous quality control measures. |
| Improve employee involvement, fostering a culture of continuous improvement. | |
What Manufacturers Demand Lean Practices from Vendors?
To maintain a lean supply chain, manufacturers need vendors and suppliers to follow the same principles. This is because of the manufacturers’ following expectations from the suppliers and vendors alike:
1. On-Time, In-Full (OTIF) Deliveries
Suppliers must ensure that materials arrive exactly when demanded or needed in the required quantity. It’s crucial because late or incomplete deliveries can disrupt production, leading to delays and increased costs.
For instance, Toyota’s supplier network follows stringent JIT protocols. It ensures a steady material flow without excess stockpiling.
2. Consistent High Quality
Lean manufacturing focuses on producing defect-free products the first time. Therefore, vendors must implement rigorous quality control to minimize defects,
This can be better understood through the example of Herman Miller, a furniture manufacturer. The company implemented lead techniques to reduce defects, improving product quality and customer satisfaction.
3. Cost Efficiency Without Compromising Quality
Lean manufacturers seek cost-effective solutions without sacrificing quality. For example, Nike collaborates with suppliers to optimize costs while maintaining sustainable production practices.
4. Waste Reduction and Sustainability Initiatives
Lean manufacturers require suppliers who prioritize waste reduction and eco-friendly practices. SunPower, a solar energy company, integrated lean principles with the circular economy to enhance sustainability and operational efficiency.
5. Agility and Responsiveness to Market Changes
Market demands can shift rapidly, and manufacturers need vendors who can be equally adept at the market fluctuating rate. Consider Intel here. Intel’s supply chain agility helped the company respond swiftly to changes in microchip demand, maintaining a competitive edge.
Market demands can shift rapidly, and manufacturers need vendors who can adapt quickly.
