The Just in Case (JIC) strategy is based on the principle of maintaining a sufficient inventory buffer to cover unexpected increases in demand or disruptions in the supply chain. Unlike the Just in Time (JIT) strategy, which advocates for minimal inventory levels to reduce carrying costs, JIC prioritizes stock availability and reliability over cost efficiency.
Key Components of the JIC Inventory Management Strategy
Safety Stock: Safety stock represents the extra inventory held above the average demand level to account for fluctuations in demand or supply. It serves as a cushion to absorb variability in customer orders, production delays, or unforeseen disruptions in the supply chain.
Lead Time: Lead time refers to the time interval between placing an order with a supplier and receiving the goods. In the JIC strategy, companies factor in lead time variability when determining the appropriate level of safety stock to hold, ensuring that sufficient inventory is available during longer-than-expected lead times.
Order Quantity: The order quantity is the amount of inventory ordered from suppliers to replenish stock levels. In JIC inventory management, companies often place larger orders to build up safety stock and minimize the risk of stockouts.
Reorder Point: The reorder point is the inventory level at which a new order is triggered to replenish stock. In the JIC strategy, the reorder point is typically set at a higher level to ensure that safety stock is available to cover demand during lead time and prevent stockouts.
Implications of the JIC Inventory Management Strategy
The JIC strategy has several implications for inventory management and business operations:
Increased Inventory Holding Costs: Holding excess inventory as safety stock incurs additional carrying costs, including storage, insurance, and obsolescence costs. Companies employing the JIC strategy must weigh the benefits of stock availability against the increased costs of holding inventory.
Reduced Stockouts: By maintaining safety stock levels, the JIC strategy helps reduce the risk of stockouts and associated costs, such as lost sales, backorders, and customer dissatisfaction. Ensuring product availability can enhance customer satisfaction and loyalty.
Trade-offs Between Cost and Service Levels: The JIC strategy requires companies to strike a balance between cost efficiency and service levels. While holding excess inventory improves product availability, it also increases inventory carrying costs and ties up working capital that could be invested elsewhere.
Supply Chain Resilience: The JIC strategy enhances supply chain resilience by providing a buffer against demand and supply uncertainties. By holding safety stock, companies can better withstand disruptions such as supplier delays, transportation issues, or sudden changes in customer demand.
Benefits of the JIC Inventory Management Strategy
Despite its challenges, the JIC strategy offers several benefits for businesses:
Improved Customer Service: Ensuring product availability through the JIC strategy enhances customer satisfaction by reducing stockouts and meeting customer demand promptly. Satisfied customers are more likely to return for future purchases and recommend the company to others.
Risk Mitigation: Holding safety stock mitigates the risk of stockouts and supply chain disruptions, thereby safeguarding against potential revenue losses and reputational damage. By maintaining buffer inventory, companies can navigate unforeseen challenges more effectively.
Flexibility and Responsiveness: The JIC strategy provides companies with greater flexibility and responsiveness to changes in customer demand or market conditions. Having excess inventory on hand allows companies to adapt quickly to fluctuations in demand or unexpected events.
Stable Supply Chain Operations: By reducing the likelihood of stockouts and backorders, the JIC strategy promotes stable and predictable supply chain operations. Suppliers can plan production and logistics more effectively, leading to smoother supply chain flows and reduced lead times.
Challenges of the JIC Inventory Management Strategy
Despite its benefits, the JIC strategy poses several challenges for businesses:
High Inventory Holding Costs: Holding excess inventory incurs additional costs, including storage, insurance, and obsolescence costs. Companies must carefully manage inventory levels to minimize carrying costs while ensuring product availability.
Risk of Inventory Obsolescence: Excess inventory increases the risk of inventory obsolescence, especially for products with short shelf lives or changing customer preferences. Companies must monitor inventory aging and implement strategies to mitigate the risk of obsolescence.
Working Capital Constraints: Tying up working capital in excess inventory limits companies’ ability to invest in other areas of the business, such as research and development, marketing, or expansion. Optimizing inventory levels is essential to free up working capital and support business growth.
Forecasting Accuracy: The success of the JIC strategy relies on accurate demand forecasting to determine the appropriate level of safety stock. Inaccurate forecasts can lead to overstocking or understocking, resulting in increased costs or missed sales opportunities.
Strategies for Successful JIC Inventory Management
To optimize the JIC strategy and mitigate its challenges, companies can adopt the following strategies:
Demand Forecasting: Invest in robust demand forecasting methods and technologies to accurately predict customer demand and optimize inventory levels. Leverage historical sales data, market trends, and customer insights to improve forecasting accuracy.
Supplier Collaboration: Collaborate closely with suppliers to reduce lead times, improve supply chain visibility, and enhance responsiveness to changes in demand. Establishing strong relationships with reliable suppliers can help mitigate supply chain risks and improve inventory management.
Inventory Optimization Tools: Implement inventory optimization tools and software solutions to analyze demand patterns, set reorder points, and optimize safety stock levels. These tools leverage data analytics and algorithms to help companies make data-driven inventory decisions.
Continuous Improvement: Regularly review and refine inventory management processes to identify inefficiencies, reduce waste, and improve overall performance. Embrace a culture of continuous improvement to drive operational excellence and adapt to changing market conditions.
Conclusion
The Just in Case (JIC) inventory management strategy offers businesses a pragmatic approach to ensuring product availability and mitigating supply chain risks. By holding safety stock to buffer against demand and supply uncertainties, companies can enhance customer satisfaction, improve supply chain resilience, and minimize the risk of stockouts. However, the JIC strategy requires careful balance and trade-offs between cost efficiency and service levels.
The supply chain is the set of steps between the sourcing, manufacturing, distribution of a product up to the steps it takes to reach the final customer. It’s the set of step it takes to bring a product from raw material (for physical products) to final customers and how companies manage those processes.
A classic supply chain moves from upstream to downstream, where the raw material is transformed into products, moved through logistics and distribution to final customers. A data supply chain moves in the opposite direction. The raw data is “sourced” from the customer/user. As it moves downstream, it gets processed and refined by proprietary algorithms and stored in data centers.
Distribution represents the set of tactics, deals, and strategies that enable a company to make a product and service easily reachable and reached by its potential customers. It also serves as the bridge between product and marketing to create a controlled journey of how potential customers perceive a product before buying it.
A distribution channel is the set of steps it takes for a product to get in the hands of the key customer or consumer. Distribution channels can be direct or indirect. Distribution can also be physical or digital, depending on the kind of business and industry.
In business, vertical integration means a whole supply chain of the company is controlled and owned by the organization. Thus, making it possible to control each step through customers. in the digital world, vertical integration happens when a company can control the primary access points to acquire data from consumers.
Horizontal integration refers to the process of increasing market shares or expanding by integrating at the same level of the supply chain, and within the same industry. Vertical integration happens when a company takes control of more parts of the supply chain, thus covering more parts of it.
By definition, a horizontal market is a wider market, serving various customer types, needs and bringing to market various product lines. Or a product that indeed can serve various buyers across different verticals. Take the case of Google, as a search engine that can serve various verticals and industries (education, publishing, e-commerce, travel, and much more).
A vertical or vertical market usually refers to a business that services a specific niche or group of people in a market. In short, a vertical market is smaller by definition, and it serves a group of customers/products that can be identified as part of the same group. A search engine like Google is a horizontal player, while a travel engine like Airbnb is a vertical player.
When entering the market, as a startup you can use different approaches. Some of them can be based on the product, distribution, or value. A product approach takes existing alternatives and it offers only the most valuable part of that product. A distribution approach cuts out intermediaries from the market. A value approach offers only the most valuable part of the experience.
Backward chaining, also called backward integration, describes a process where a company expands to fulfill roles previously held by other businesses further up the supply chain. It is a form of vertical integration where a company owns or controls its suppliers, distributors, or retail locations.
A market type is a way a given group of consumers and producers interact, based on the context determined by the readiness of consumers to understand the product, the complexity of the product; how big is the existing market and how much it can potentially expand in the future.
Psychosizing is a form of market analysis where the size of the market is guessed based on the targeted segments’ psychographics. In that respect, according to psychosizing analysis, we have five types of markets: microniches, niches, markets, vertical markets, and horizontal markets. Each will be shaped by the characteristics of the underlying main customer type.
According to the book, Unlocking The Value Chain, Harvard professor Thales Teixeira identified three waves of disruption (unbundling, disintermediation, and decoupling). Decoupling is the third wave (2006-still ongoing) where companies break apart the customer value chain to deliver part of the value, without bearing the costs to sustain the whole value chain.
Disintermediation is the process in which intermediaries are removed from the supply chain, so that the middlemen who get cut out, make the market overall more accessible and transparent to the final customers. Therefore, in theory, the supply chain gets more efficient and, all in all, can produce products that customers want.
Reintermediation consists in the process of introducing again an intermediary that had previously been cut out from the supply chain. Or perhaps by creating a new intermediary that once didn’t exist. Usually, as a market is redefined, old players get cut out, and new players within the supply chain are born as a result.
As startups gain control of new markets. They expand in adjacent areas in disparate and different industries by coupling the new activities to benefits customers. Thus, even though the adjunct activities might see far from the core business model, they are tied to the way customers experience the whole business model.
The bullwhip effect describes the increasing fluctuations in inventory in response to changing consumer demand as one moves up the supply chain. Observing, analyzing, and understanding how the bullwhip effect influences the whole supply chain can unlock important insights into various parts of it.
Dropshipping is a retail business model where the dropshipper externalizes the manufacturing and logistics and focuses only on distribution and customer acquisition. Therefore, the dropshipper collects final customers’ sales orders, sending them over to third-party suppliers, who ship directly to those customers. In this way, through dropshipping, it is possible to run a business without operational costs and logistics management.
Consumer-to-manufacturer (C2M) is a model connecting manufacturers with consumers. The model removes logistics, inventory, sales, distribution, and other intermediaries enabling consumers to buy higher quality products at lower prices. C2M is useful in any scenario where the manufacturer can react to proven, consolidated, consumer-driven niche demand.
Transloading is the process of moving freight from one form of transportation to another as a shipment moves down the supply chain. Transloading facilities are staged areas where freight is swapped from one mode of transportation to another. This may be indoors or outdoors, depending on the transportation modes involved. Deconsolidation and reconsolidation are two key concepts in transloading, where larger freight units are broken down into smaller pieces and vice versa. These processes attract fees that a company pays to maintain the smooth operation of its supply chain and avoid per diem fees.
Break bulk is a form of shipping where cargo is bundled into bales, boxes, drums, or crates that must be loaded individually. Common break bulk items include wool, steel, cement, construction equipment, vehicles, and any other item that is oversized. While container shipping became more popular in the 1960s, break bulk shipping remains and offers several benefits. It tends to be more affordable since bulky items do not need to be disassembled. What’s more, break bulk carriers can call in at more ports than container ships.
Cross-docking is a procedure where goods are transferred from inbound to outbound transport without a company handling or storing those goods. Cross-docking methods include continuous, consolidation, and de-consolidation. There are also two types of cross-docking according to whether the customer is known or unknown before goods are distributed. Cross-docking has obvious benefits for virtually any industry, but it is especially useful in food and beverage, retail and eCommerce, and chemicals.
The Toyota Production System (TPS) is an early form of lean manufacturing created by auto-manufacturer Toyota. Created by the Toyota Motor Corporation in the 1940s and 50s, the Toyota Production System seeks to manufacture vehicles ordered by customers most quickly and efficiently possible.
Six Sigma is a data-driven approach and methodology for eliminating errors or defects in a product, service, or process. Six Sigma was developed by Motorola as a management approach based on quality fundamentals in the early 1980s. A decade later, it was popularized by General Electric who estimated that the methodology saved them $12 billion in the first five years of operation.
Scientific Management Theory was created by Frederick Winslow Taylor in 1911 as a means of encouraging industrial companies to switch to mass production. With a background in mechanical engineering, he applied engineering principles to workplace productivity on the factory floor. Scientific Management Theory seeks to find the most efficient way of performing a job in the workplace.
Poka-yoke is a Japanese quality control technique developed by former Toyota engineer Shigeo Shingo. Translated as “mistake-proofing”, poka-yoke aims to prevent defects in the manufacturing process that are the result of human error. Poka-yoke is a lean manufacturing technique that ensures that the right conditions exist before a step in the process is executed. This makes it a preventative form of quality control since errors are detected and then rectified before they occur.
A Gemba Walk is a fundamental component of lean management. It describes the personal observation of work to learn more about it. Gemba is a Japanese word that loosely translates as “the real place”, or in business, “the place where value is created”. The Gemba Walk as a concept was created by Taiichi Ohno, the father of the Toyota Production System of lean manufacturing. Ohno wanted to encourage management executives to leave their offices and see where the real work happened. This, he hoped, would build relationships between employees with vastly different skillsets and build trust.
Jidoka was first used in 1896 by Sakichi Toyoda, who invented a textile loom that would stop automatically when it encountered a defective thread. Jidoka is a Japanese term used in lean manufacturing. The term describes a scenario where machines cease operating without human intervention when a problem or defect is discovered.
The andon system alerts managerial, maintenance, or other staff of a production process problem. The alert itself can be activated manually with a button or pull cord, but it can also be activated automatically by production equipment. Most Andon boards utilize three colored lights similar to a traffic signal: green (no errors), yellow or amber (problem identified, or quality check needed), and red (production stopped due to unidentified issue).
