Demand forecasts can be a powerful asset for inventory-based businesses. They can anticipate customer needs, align production with demand, minimize waste and costs, and improve profit margins. However, demand forecasts need to be as precise as possible to truly move the needle and lead to optimal business outcomes. Due to today’s complex and volatile business environment, accurate demand forecasting in the supply chain is challenging.
Think about it: Modern businesses operate in a supply chain marked by rapid market fluctuations, unpredictable consumer behavior, global eCommerce trends, and supply chain disruptions. Without accurate forecasting, businesses risk overstocking their inventory, which can lead to increased holding costs, or understocking, which can result in missed sales opportunities and dissatisfied customers. However, with specific demand forecasting techniques and best practices, businesses can produce the most accurate forecasts possible to optimize their supply chains and stay ahead in the market.
The State of Demand Forecasting Today
Demand forecasting in the supply chain is a well-established process that has evolved significantly over the years. Most recently, new changes have been driven by advancements in technology, data analytics, and artificial intelligence, which experts refer to as a “digital shake-up.”
Here are some of the recent trends impacting the demand forecasting space.
1. Growing supply chain risks
Global supply chains are more interconnected than ever, making them highly susceptible to disruptions and volatility. Events like the COVID-19 pandemic, geopolitical tensions, and raw materials shortages have highlighted the risks of the modern supply chain. One study found that nine in ten businesses encountered supply chain challenges in 2024.
2. The rise of artificial intelligence and big data
Traditionally, forecasting methods have relied solely on historical sales data and simple statistical models. Today, businesses are leveraging big data, artificial intelligence (AI), and machine learning to analyze vast datasets, identify patterns, and predict demand more accurately. For example, AI-powered models can incorporate external variables such as weather conditions, social media trends, and economic indicators, providing a more comprehensive view of expected demand. Research shows that nearly 90% of large businesses have at least “experimented” with AI in their supply chains.
3. Real-time and automated demand forecasting
With the growth of cloud computing and Internet-of-Things (IoT) technologies, companies are moving towards real-time demand forecasting. These automated forecasting systems can process data continuously, adjusting predictions dynamically based on changing conditions in real time. This valuable shift enables businesses to spot divergences from forecasts earlier and make data-driven decisions more quickly.
4. Integrated demand forecasting
Demand forecasting is no longer a standalone process. Instead, it’s typically a feature included in advanced inventory management software, including tools for inventory analysis, supplier performance monitoring, and replenishment planning. This integrated approach to demand forecasting gives decision-makers a holistic view of their inventory and operations. These tools typically display forecasts and other insights in user-friendly charts, graphs, and customized views to improve the way you understand your forecast and put it to work.
Benefits of Accurate Demand Forecasts
Highly accurate demand forecasting in the supply chain is vital for businesses that want to remain competitive and best meet customer needs.
Here are the key benefits of maximizing the accuracy of demand forecasts:
1. Optimized inventory management
As we touched on, accurate demand forecasts play a key role in preventing overstocking and stockouts, which cost businesses $1.7 trillion annually. This is important for avoiding holding excessive inventory while ensuring you always have products available when customers need them. Additionally, accurate demand forecasts enhance warehouse efficiency by aligning inventory levels with actual demand trends.
2. Cost savings across the supply chain
Aside from lowering holding costs, accurate demand forecasts contribute to cost savings in many other ways. For example, businesses can reduce costly “rushed” orders from last-minute inventory adjustments. Accurate demand forecasts also help minimize costs associated with waste and obsolescence, especially for perishable goods, seasonal products, or industries with short product life cycles.
3. Improved production planning and efficiency
Accurate demand forecasts allow businesses to align their product schedules with actual demand, leading to smoother operations. This can have trickle-down benefits, such as improved staff scheduling: Businesses can bring on more team members during busy periods and cut back on staffing when business is expected to be leaner.
4. Enhanced supplier and logistics coordination
With accurate demand forecasts, businesses can better plan with suppliers and logistics providers. For example, decision-makers can help logistics teams optimize transportation routes and delivery schedules, cutting operational expenses and improving lead times. Plus, instead of being caught off-guard by demand fluctuations, accurate demand forecasts allow you to anticipate consumer habits and to coordinate with your suppliers accordingly.
5. Increased customer satisfaction and retention
Accurate demand forecasts in the supply chain also allow businesses to provide the best customer experience possible. With reduced stockouts and shorter lead times, businesses can reduce customer frustrations and ensure the smooth flow of goods. These demand forecasts also become particularly useful when it comes to more effectively meeting seasonal and promotional demands.
Best Practices for Improving Forecast Accuracy
Accurate demand forecasts in the supply chain allow companies to streamline their operations, reduce unnecessary costs, and build stronger relationships with customers and suppliers. However, achieving maximum forecast accuracy requires advanced techniques, high-quality data, and strategic management.
Here are best practices you can use to improve forecast accuracy in your business:
1. Prioritize data quality and consistency
The foundation of any reliable forecast is high-quality data. Because of this, you should always ensure data is complete, accurate, and as up-to-date as possible. You should invest in new systems (such as IoT devices to improve real-time inventory tracking). Also, eliminate data inconsistencies by regularly auditing, cleansing, and validating datasets.
2. Select the proper forecasting methods for your needs
No single forecasting model is perfect. To maximize forecast accuracy, combine forecasting methods that best suit your needs. For example, you can wind up with the most accurate forecasts by combining qualitative methods (expert judgment, market research) and quantitative methods (statistical models, machine learning). Continuously test different forecasting models and adjust your choices based on performance.
3. Implement real-time forecasting and automation
Real-time demand forecasting and AI-powered tools enable businesses to adapt quickly to fluctuations and forecast deviations. Consider using AI tools that analyze real-time sales and inventory data and implementing automated systems that dynamically adjust predictions based on real-world factors.
4. Choose an advanced inventory management solution.
Instead of deploying fragmented technologies, consider deploying a comprehensive and connected advanced inventory management solution. For example, StockIQ has features for demand forecasting, monitoring supplier performance, and analyzing the state of your inventory. You can also see crucial insights in an easy-to-read dashboard, which can help you make rapid-fire decisions.
5. Regularly review and adjust forecasts
Even the best forecast models need continuous monitoring and refinement. Key performance indicators such as Mean Absolute Percentage Error (MAPE) should be used to assess forecast accuracy regularly. Also, compare actual demand with forecasted values and adjust your models accordingly.
By adopting the right technologies and best practices, inventory-based businesses can improve their demand forecast accuracy, leading to more efficient supply chain operations, reduced costs, and improved customer satisfaction.
