What is inventory management?
According to IBM, inventory management is “the tracking of inventory from manufacturers to warehouses and from these facilities to a point of sale.” The goal of inventory management is to have the right products in the right place at the right time.
Inventory management can be divided into four types, depending on the stage of the product life cycle:
- Raw materials: These are unprocessed materials that are used to produce finished products. For example, metals, plastics, and oils.
- Parts and components: These are parts that are recognizable on their own before and after product completion. For example, screws, bolts, hinges, and batteries.
- Work in progress (WIP): These are products that are currently in production and may include raw materials, parts and components, packaging materials, and more.
- Finished products: These are completed items that are ready to be distributed and sold. For example, clothing, electronics, furniture, and books.
What are the benefits of inventory management?
Inventory management has several benefits for businesses of any size and industry. Some of the benefits are:
- Improved customer satisfaction: By having the right products available at the right time and place, businesses can meet customer demand and expectations. This can lead to increased sales, loyalty, and referrals.
- Reduced costs: By optimizing the inventory levels and avoiding overstocking or understocking, businesses can reduce the costs of storage, handling, transportation, insurance, spoilage, theft, damage, and obsolescence. This can also improve the cash flow and working capital of the business.
- Increased efficiency: By streamlining the inventory processes and using technology such as barcode scanners, RFID tags, or inventory management software, businesses can improve the accuracy, speed, and visibility of their inventory operations. This can also reduce human errors, wastage, and delays.
- Enhanced competitiveness: By managing inventory effectively, businesses can gain a competitive edge over their rivals by offering better quality, variety, availability, and prices of their products. This can also help them respond faster to market changes and customer preferences.
What are some techniques for inventory management?
There are many techniques for inventory management that vary depending on the business needs, goals, and resources. Some of the common techniques are:
- Just-in-time (JIT) inventory management: This technique aims to minimize the inventory levels by ordering or producing only what is needed when it is needed. This reduces the storage costs and risks of holding excess or obsolete inventory. However, this technique requires a high level of coordination with suppliers and customers and may be vulnerable to disruptions or fluctuations in demand or supply.
- Materials requirement planning (MRP) inventory management: This technique uses a computerized system to calculate the optimal quantity and timing of ordering or producing each item based on the forecasted demand, the current inventory levels, the lead time, and the production capacity. This helps to plan ahead and avoid shortages or surpluses. However, this technique may be complex and costly to implement and may rely on inaccurate or outdated data.
- Economic order quantity (EOQ) inventory management: This technique uses a mathematical formula to determine the optimal order quantity that minimizes the total cost of ordering and holding inventory. The formula takes into account the demand rate, the ordering cost per order, the holding cost per unit per period, and the discount rate (if any). However, this technique assumes that demand is constant and known, that ordering cost is fixed, and that there are no stockouts or shortages.
- Days sales of inventory (DSI) inventory management: This technique measures how long it takes for a business to sell its average inventory level. It is calculated by dividing the average inventory by the cost of goods sold (COGS) per day. A lower DSI indicates a faster turnover of inventory, which means less storage costs and more cash flow. A higher DSI indicates a slower turnover of inventory, which means more storage costs and less cash flow. However, this technique does not consider the seasonality or variability of demand or supply, or the differences in product categories or margins.
Tips
- Align your inventory management strategy with your business goals and customer needs
- Use data and analytics to forecast demand and plan supply
- Use technology and tools to automate and streamline your inventory processes
- Use inventory management techniques that suit your business type, size, and industry
- Train and empower your staff to manage inventory efficiently and effectively
- Communicate and collaborate with your suppliers and customers to improve visibility and coordination
- Review and improve your inventory management practices regularly
Managing Inventory: A Statistical Report
Inventory management is the process of ordering, storing, using, and selling a company’s inventory. This includes the management of raw materials, components, and finished products, as well as warehousing and processing of such items. Inventory management is a critical element of the supply chain, as it affects the efficiency, profitability, and customer satisfaction of a business.
Global Demand for Inventory Management
The global demand for inventory management has increased in recent years due to various factors, such as:
- The growth of e-commerce and omnichannel retailing, which require fast and accurate fulfillment of orders across multiple channels and locations.
- The emergence of new technologies, such as artificial intelligence (AI), blockchain, internet of things (IoT), and cloud computing, which enable real-time visibility, automation, and optimization of inventory processes.
- The impact of the COVID-19 pandemic, which disrupted the supply and demand patterns of many industries and highlighted the need for agile and resilient inventory management systems.
According to a report by Grand View Research, the global inventory management software market size was valued at USD 2.66 billion in 2020 and is expected to grow at a compound annual growth rate (CAGR) of 9.7% from 2021 to 2028.
Inventory Management Methods and Techniques
There are different types of inventory management methods and techniques that businesses can use to effectively track and control their inventory levels. Some of the most common ones are:
- Just-in-time (JIT) inventory management: This method aims to minimize inventory holding costs by ordering or producing only the amount of inventory that is needed to meet customer demand at a given time.
- Materials requirement planning (MRP) inventory management: This method uses historical sales data and forecasting techniques to calculate the optimal amount and timing of inventory orders based on the expected demand for finished products.
- Economic order quantity (EOQ) inventory management: This method determines the optimal order quantity that minimizes the total cost of ordering and holding inventory, taking into account factors such as demand rate, ordering cost, and holding cost.
- Days sales of inventory (DSI) inventory management: This method measures the average number of days that a company takes to sell its inventory, indicating its inventory turnover rate and liquidity.
Each of these methods has its pros and cons, depending on a company’s needs, industry, and market conditions. Therefore, businesses should carefully evaluate their inventory management goals and strategies before choosing a suitable method or technique.
