Backorders occur when customer demand exceeds the available supply or production capacity and at the same time there is a stock out preventing fulfilling the customer demand by inventory.
This situation arises due to various constraints, such as limited manufacturing resources, supply chain disruptions, or unexpected spikes in customer orders. Backorders represent unfulfilled customer orders placed on hold until the necessary inventory or production capacity becomes available.
Modeling backorders and optimizing its fulfillment is crucial for businesses to increase revenue, minimize cost, manage customer expectations, and minimize the impact of supply-demand mismatches.
There are several approaches to modeling backorders, each with its own advantages and considerations.
Keep reading to know what causes backorders and how Sophus X can help you manage them.
Impact of Factory Equipment Maintenance
Factories rely heavily on their production equipment to meet customer demand. However, even with preventive maintenance schedules, equipment can experience unexpected breakdowns or require more extensive repairs than anticipated. Planned maintenance shutdowns, while scheduled in advance, can also limit production capacity during those periods.
When key pieces of equipment go offline, whether planned or unplanned, it directly reduces the factory’s output capabilities. This lower production capacity may not fulfill all outstanding customer orders within the desired timeframe. As a result, some orders inevitably get delayed and become backorders.
For example, if a factory has an assembly line responsible for 50% of its total output, and that line requires a two-week maintenance overhaul, the factory’s capacity during those two weeks is effectively cut in half. Any orders that cannot be produced with the remaining 50% capacity will likely become backorders until the assembly line returns to full operation.
Unplanned equipment failures can have an even more disruptive impact. A sudden breakdown of critical machinery may halt production entirely for a period until the repairs are completed. This unplanned downtime can quickly lead to a backlog of unfulfilled orders as the factory falls behind its production schedule.
Spikes in Customer Demand
Spikes in customer demand can quickly overwhelm production capacity, leading to backorders. These surges can stem from various factors, such as seasonal trends, viral product launches, or unexpected market events.
For example, during the holiday season, retailers may experience a significant increase in demand for popular toys, electronics, or other gift items. If the production capacity is not scaled up in advance, manufacturers may struggle to keep up with the influx of orders, resulting in backorders.
Another scenario that can cause demand spikes is the launch of a highly anticipated product. When a new gadget, video game console, or fashion item hits the market and generates substantial buzz, demand can skyrocket, outpacing the manufacturer’s ability to produce enough units to meet the initial demand.
Viral trends on social media can also drive sudden and unexpected demand surges. If a particular product or brand goes viral, it can create a frenzy of orders that the company may not have anticipated, leading to backorders until production can catch up.
In some cases, external events or market conditions can contribute to demand spikes. For instance, a shortage of a particular raw material or component used in various products could lead to panic buying and increased demand for products that utilize that material or component.
Adjust Customer/Order Status with Sophus X
When production capacity is constrained due to factors like equipment maintenance or demand surges, and there isn’t enough inventory to cover the demand you may need to strategically abandon certain orders to optimize revenue and fulfillment with what you have. This can be modeled by adjusting the status of customers in the Sites table and the status of their orders in the Customer Orders table to “Consider”.
Sophus X provides a smooth UI where marking an order as “Consider” flags it for potential dropping by the optimization model. However, you have control over what orders get prioritized through two key levers:
- Minimum Fulfillment Ratio (MinRatio): In the Customer Orders table, you can set a minimum percentage that each order must be fulfilled. For example, a MinRatio of 0.8 means at least 80% of the order quantity must be met.
- Unit Lost Sales Penalty Cost (UnitLostSalesPenaltyCost): This parameter in the Customer Orders table allows you to assign a penalty cost for each unit of a product that is abandoned from an order. Orders with higher penalty costs will be prioritized for fulfillment by the model.
By adjusting the MinRatio and UnitLostSalesPenaltyCost values, you can control which orders get dropped and to what extent based on your business priorities on revenue, profit or other considerations.
Orders failing to meet the MinRatio or with lower penalty costs are more likely to be abandoned when production capacity and on-hands inventory is limited.
In addition to dropped orders, Sophus X can also consider backorders by setting the “DaysAllowedDelay” and “DaysAllowedEarly”.
Imagine because of the lack of capacity during the peak season, some orders may get delayed till after the peak season with a reduced margin.
Or because of the limited storage space, a business might deliver an order early to a customer to free up the space. The order table also allows users to define a penalty cost per period per unit.
Viewing Outputs
In the Output Network Cz Shipments table, you can view crucial details about order fulfillment after the model has run.
This table provides visibility into the quantity demanded for each product by each customer, the quantity that was successfully fulfilled, and any quantities that had to be abandoned due to capacity constraints.
By examining this table, you can gain insights into which customers and products experienced backorders or partial fulfillment. The abandoned quantity represents potential lost sales or revenue, while the fulfilled quantity reflects the actual orders that were successfully processed and delivered to customers.
Importance of Qualitative Factors in Back Order Modeling
While numerical factors like costs, capacities, and penalties are crucial inputs for back-order modeling, it’s essential to consider qualitative factors as well. These non-numerical considerations can significantly impact decision-making and the overall success of your back-order management strategy.
Customer Value and Retention: Certain customers may hold greater strategic importance or revenue potential for your business. Prioritizing their orders, even at the expense of higher immediate costs, can foster long-term customer loyalty and retention. Consider segmenting customers based on their lifetime value or strategic importance, and adjust back order policies accordingly.
Product Prioritization: Not all products are created equal. Some may be flagship offerings, seasonal items, or have higher profit margins. Prioritizing the fulfillment of these products can help maximize revenue and protect your brand reputation. Develop a product prioritization framework that considers factors like profitability, strategic importance, and customer demand.
Contractual Obligations: Existing contracts or service-level agreements (SLAs) with customers may stipulate specific delivery timelines or penalties for late or missed orders. Failing to meet these obligations can result in financial penalties, damaged relationships, or even legal consequences. Ensure that your backorder management strategy accounts for these contractual obligations and prioritizes orders accordingly.
Brand Reputation and Customer Experience: Backorders can negatively impact customer satisfaction and brand perception, especially if handled poorly. Consider the potential long-term damage to your brand reputation when making backorder decisions. Prioritize transparency, clear communication, and exceptional customer service to mitigate the negative impact of backorders on customer experience.
Competitive Landscape: In highly competitive markets, backorders can provide an opportunity for competitors to swoop in and capture dissatisfied customers. Evaluate the competitive landscape and the potential consequences of losing customers to rivals when making back-order decisions.
By considering these qualitative factors alongside numerical inputs, you can develop a more well-rounded and effective backorder management strategy that balances short-term operational constraints with long-term strategic goals and customer relationships.
Understanding the Financial Impacts of Backorders
Backorders can have significant financial implications for businesses.
Lost Sales Revenue
One of the primary costs associated with backorders is lost sales revenue. When a customer’s order cannot be fulfilled due to inventory constraints, the sale is effectively lost, resulting in missed revenue opportunities. This can be particularly detrimental for businesses operating in competitive markets, as customers may turn to alternative suppliers to meet their needs.
Loss of Customer Goodwill
Another financial impact of backorders is the potential loss of customer goodwill. Customers expect timely and reliable service, and when their orders are delayed or unfulfilled, it can lead to frustration and dissatisfaction. This negative experience can damage the company’s reputation and make it more challenging to retain existing customers or attract new ones.
Additional Costs
In some cases, businesses may incur additional costs related to expediting fees or rush shipping charges to minimize the impact of backorders. While these fees can help mitigate the consequences of backorders, they can also eat into profit margins and strain operational budgets.
Trade-offs with Other Business Priorities
Furthermore, backorders can create trade-offs with other business priorities. For example, allocating resources to address backorder situations may divert attention and funds from other critical areas, such as product development, marketing, or expansion efforts. Businesses must carefully balance these competing priorities to ensure long-term success and growth.
Conclusion
In conclusion, effectively managing backorders is crucial for maintaining customer satisfaction and operational efficiency. By using advanced modeling capabilities, businesses can proactively address constraints, optimize fulfillment strategies, and minimize the impact of backorders on their operations.
