What are the Benefits and Limitations of Forecasting? (2024)

Forecasting plays a critical role in tracking a company’s supply chain by providing insights into future demand patterns, allowing for businesses to anticipate the needs of the customer and plan their supply chain activities. During my internship at Apex Marketing and Sales, I have had the opportunity to work on many supply plans through Walmart’s “Luminate.” I create these supply plans so that suppliers can forecast their future orders more efficiently, and can enable proactive decision making. Here are some ways that forecasting helps track a company’s supply chain:

1. Demand Planning: Forecasting helps in estimating future demand for products or services based on historical data, market trends, customer behavior, and other factors. By understanding demand fluctuations, companies can adjust their production schedules, inventory levels, and distribution processes to meet customers needs effectively.
2. Inventory Management: Accurate forecasting allows companies to optimize inventory levels by ensuring that they have enough stock to fulfill customer orders while minimizing inventory holding cost. By tracking demand forecasts closely, companies can avoid stock outs and overstock situations, improving operational efficiency and reducing carrying costs.
3. Procurement and Supplier Management: Forecasting helps companies anticipate raw material and component requirements, enabling them to coordinate with suppliers and ensure timely delivery inputs. By tracking demand forecasts with suppliers, companies can establish collaborative relationships, negotiate favorable terms, and mitigate supply chain risks associated with shortages or disruptions.
4. Transportation and Logistics: Forecasting helps assist companies in planning transportation and logistic operations by predicting the volume and timing of product shipments. By analyzing demand forecasts, companies can optimize routes, modes of transportation, and distribution networks to ensure timely delivery while minimizing transportation costs and environmental impact.
5. Risk Management: Forecasting helps companies identify potential risks and uncertainties in the supply chain, such as supplier disruptions, market volatility, or unexpected changes in customer demand. By incorporating risk factors into forecasting models, companies can develop contingency plans, diversified sourcing strategies, and enhance their supply chain.

Overall, forecasting serves as a strategic tool for tracking a company’s supply chain by providing visibility into future demand dynamics, enabling proactive decision making, and optimizing supply chain processes to meet customer requirements efficiently. However, there are some instances when forecasting can present challenges or drawbacks:

1. Inaccurate Forecasts: One of the primary risks associated with forecasting is the potential for inaccuracies. If forecasts are based on incomplete data or unreliable models, they may lead to incorrect predictions of future demand. Which can result in overstocking of stock outs within the supply chain
2. Bullwhip Effect: Forecasting errors can amplify the bullwhip effect, causing demand distortion as information moves upstream in the supply chain. Inaccurate forecasts at the retail level can lead to exaggerated order fluctuations at the wholesale, manufacturing, and supplier levels. Resulting in inefficiencies, excess inventory, and increased costs.
3. Supply Chain Disruptions: Forecasting may not account for unpredictable events or supply chain disruptions, such as natural disasters, geopolitical risks, or supplier failures. In order to mitigate the impact of disruptions on their supply chains, companies create a contingency plan and response mechanisms.
4. Costs of Forecasting: Developing and maintaining forecasting systems can be resource-intensive and costly for companies, requiring investments in technology, data analytics, and human resources. If the benefits for forecasting do not outweigh the associated costs, it may be a burden rather than a value-added tool within the supply chain.

My internship at Apex Marketing and Sales this semester has helped me realize the importance of tracking a company’s supply chain, and has allowed me to understand how forecasting can be a valuable tool for a company. Companies should adopt a balanced approach to forecasting that incorporates both quantitative and qualitative factors, embraces uncertainty, and fosters agility and resilience within the supply chain to effectively manage risks and capitalize on opportunities in the dynamic business environment of the world today.
