What is the Difference Between a Shortage and a Scarcity
With supply chain bottlenecks of both goods and services running rampant post-pandemic, the term “shortages” is quite common to hear in the manufacturing industry. But exactly what is a shortage and why are they such a big deal?
What is a shortage?
A shortage refers to a situation where demand exceeds supply for a particular product or material. It’s usually temporary and caused by specific disruptions like supply chain issues, labor shortages, or changes in consumer demand. Shortages can be managed by boosting production, finding alternate suppliers, rationing existing supply, or waiting for the market to correct itself.

Scarcity refers to an ongoing imbalance between limited resources and unlimited human wants. Resources like oil, minerals, and land are inherently scarce due to finite supply. Scarcity leads to higher prices as demand exceeds what is available. Companies mitigate scarcity risk by securing contracts and long-term agreements for needed resources, developing substitutes, improving resource efficiency in operations and production, and forecasting future demand more accurately.
To manage both short-term shortages and long-term scarcity, manufacturers need end-to-end visibility and early warning signs. Analytics and inventory optimization software can help model demand, detect potential shortages, and reduce excess stock. Building redundancies into the supply chain through additional suppliers and strategic stock levels creates a buffer. Cross-training employees and flexible production approaches also help adjust to disruptions. With proactive mitigation measures, companies can reduce their exposure to shortages and resource scarcity.
The graphs below illustrate these concepts. Demand slopes downward for a normal good because as the price increases, the demand for the product decreases. The opposite is true for supply, as the price increases suppliers want to produce and sell more. As the price changes, supply and demand move along their respective curves.
Manufacturers think of shortages more as the actual lack of a part or product. Examples such as the chip crisis or the infamous toilet paper shortage of 2020 continue to pop up in the post-pandemic supply chain. Shortages also occur in the service industry, like the much-discussed shortage of long-haul drivers.
Shortage management involves reviewing on-hand inventory, supply, and demand, and adjusting the order schedule to ensure that production can continue. Without proper shortage management, shortages will continue to wreak havoc throughout the supply chain, costing companies extra in excess inventory, expediting fees, missed orders, and more.
What is the cost of a shortage?
The costs of shortages are typically measured in some type of opportunity cost—what was lost from not completing a sale or loss of future business. While the potential negative impacts are vast, there are three main costs of shortages.
1. Loss of Sale
When a shortage occurs, the product is more likely to reach its end destination late. Some consumers or customers will wait out the later delivery time, but others will cancel their order and expedite the part or product from elsewhere, resulting in a lost sale. Lost sales have a more immediate cost associated with them because businesses are losing the money directly associated with that particular sale.
2. Loss of Customer
When products or parts do not show up on time, it’s safe to say customers are not happy. Even so much as one late delivery can drive customers away from the competition. To recognize the cost of losing customers, companies cannot look at merely one lost cost like the loss of a sale, but all of the potential future purchases that customers would have made.
3. Loss of Goodwill
The loss of goodwill basically amounts to the loss of a good relationship with a customer. While they may still buy from a company, they may not buy as much or as frequently. They are also less likely to recommend that company to their networks and will not likely carry that supplier as they move jobs throughout their career.
The most substantial direct cost of shortages, however, is expediting. In order to prevent the loss of a sale, customer, or goodwill, companies expedite the parts from a different supplier. This typically allows the company to complete the sale on time but will cost extra in shipping and delivery fees.
