Safety Stock: Inventory Management Concept to Overcome Market Fluctuations

Posted on

Safety Stock

Safety stock (Inventory Management) is a very important concept in  inventory management of a business. In a dynamic business world, managing inventory is the key to success. Inventory Management refers to inventory reserves that have an important role in maintaining smooth business operations.

How can you optimally utilize this concept? We will explore that in this article. Here,  TransTRACK will discuss in depth what safety stock is, its benefits for businesses, and how to calculate and manage it efficiently. Let’s listen to the information carefully!

What is Safety Stock?

Safety stock is the amount of extra inventory that a business maintains as a backup to cope with fluctuations in demand or availability of raw materials. It is a strategy used to avoid stock shortages that can cause problems in the supply chain. Inventory Management is an anticipatory measure that allows businesses to keep operating smoothly even in unexpected situations.

The idea behind Inventory Management is to provide assurance that the business has enough inventory to cope with spikes in demand or disruptions in the supply chain without having to stop operations.

In other words, Inventory Management is a proactive measure that helps businesses deal with uncertainty in supply and demand. By managing them carefully, businesses can maintain smooth operations, meet customer demands, and reduce risks due to market fluctuations. Inventory Management is one of the key elements in an efficient inventory management strategy in a highly dynamic business world.

Benefits of Safety Stock for Business

The benefits of safety stock for businesses are very important in maintaining smooth operations and customer satisfaction. Here are some complete explanations of the benefits:

Avoiding Stock Shortages

A key benefit of Inventory Management is avoiding stock shortages. A stock shortage is a situation where a business does not have enough  stock to meet customer demand.

Out of stock can have a devastating impact on a business, as it can lead to delays in deliveries, lower customer satisfaction, and financial losses. Inventory Management provides assurance that there is always enough inventory, even if demand spikes suddenly.

Coping with High Demand

Successful businesses often face high demand for their products in the market. This can be caused by several factors such as seasonal influences, market trends, or unexpected events.

Inventory Management allows businesses to cope with these fluctuations without having to stop production or limit sales. In other words, businesses can remain responsive to unexpected changes in customer demand.

Reduce the Risk of Disruptions in the Supply Chain

The supply chain or  supply chain can be affected by various issues, such as delays in deliveries from suppliers, damage to goods during transportation, or changes in trade policies.

Inventory Management serves as a backup that can be used when there is a disruption in the supply chain. With safety stock in place, businesses can continue their operations without being unduly affected by these disruptions.

Flexibility in Production

Inventory Management can give businesses flexibility in planning the production of goods. Without safety stock, businesses are required to operate very strictly according to actual demand.

This can cause stress on the production process and reduce flexibility. With Inventory Management, the process of producing goods can be carried out freely and provide room for more consistent and planned production.

Increased Customer Satisfaction

Ultimately, the most important benefit of Inventory Management is to increase customer satisfaction. By having enough inventory, businesses can provide maximum service to customers.

When a company has Inventory Management, products can be delivered on time to customers, reduce customer disappointment due to late delivery, and maintain good relationships with customers.

Safety Stock Formula

Calculating Inventory Management involves various factors, including demand levels, delivery times, and desired service levels. One of the commonly used formulas for calculating Inventory Management is Heizer and Render:

Safety Stock = (Z-score x √Lead Time x Demand Standard Deviation) + Average Demand

In this formula:

  • Z-score is a statistical value that relates to the desired confidence level.
  • Lead Time is the time required to obtain additional inventory after ordering.
  • Demand Standard Deviation is the degree of variation in demand.
  • Average Demand is the average demand during Lead Time.

How to Calculate Safety Stock

To calculate Inventory Management appropriately, the following steps can be followed:

  • Identify Key Variables: First, identify key variables such as the level of demand, delivery time, and desired level of trust.
  • Calculate the Z-score: Calculate the Z-score based on the desired confidence level. The Z-score will help determine how much standard deviation should be factored into the safety stock.
  • Calculate Standard Deviation: Calculate the standard deviation of demand over the Lead Time. This will allow you to estimate fluctuations in demand.
  • Calculate Inventory Management: Finally, use the safety stock formula mentioned earlier to calculate the amount of safety stock required.

In inventory management, safety stock is a component that should not be overlooked. With a good understanding of its benefits, businesses can optimize the use of safety stock to support growth and smooth operations.

The implementation of  Logistic Service Integrator (LSI) technology from  TransTRACK is one of the innovative and efficient solutions to optimize safety stock in inventory management. LSI is a system that integrates various logistics and information services in one centralized platform, enabling businesses to manage inventory, supply chain, and delivery more effectively.

In a complex inventory management chain, implementing Logistic Service Integrator technology is a wise move. LSI enables businesses to optimize their safety stock, improve operational efficiency, and ensure customer satisfaction. In addition, human errors can be reduced, product management forecasts become more accurate, and uncertainties in the supply chain can be better handled. LSI technology plays an important role in facing inventory challenges in the fast-changing business era.
