Assets vs. Asset Stock vs. Inventory: Key Differences for Maintenance Teams

In maintenance, why would you need to know the differences between assets, asset stock, and inventory? Each represents valuable items a company owns. You should understand the distinctions for better operations. That's what this article will delve into. Read on to discover:

• Defining the Landscape: Assets, Asset Stock, and Inventory.
• Why Maintenance Needs to Distinguish Between Assets, Asset Stock, and Inventory.
• Common Challenges in Defining Assets and Inventory.
• Industry Examples: Highlighting the Differences.
• How CMMS Software Helps Manage Assets and Inventory Efficiently.

Defining the Landscape: Assets, Asset Stock, and Inventory

Before we highlight any differences, let's start by defining each term.

Assets - A broad term encompassing anything a company owns that holds economic value. This includes tangible and intangible resources. Tangible assets represent physical items like buildings, machinery, equipment, furniture, and vehicles. Intangible assets consist of non-physical but valuable quotients, such as patents, copyrights, trademarks, and brand reputations.

Asset Stock - This subcategory of assets refers to a group of identical items used in operations. These items typically have a longer lifespan and you don't track them individually. Examples include office chairs, desks, cables, tools, and uniforms. While valuable, their individual costs lack significance for individual tracking.

Inventory - Inventory refers to the stock of raw materials, work-in-progress goods, and finished products a company holds for sale or consumption in the production process. View these as "current assets." This means you expect to sell or use them within a year. Inventory constantly fluctuates as the company purchases, uses, or sells them.

Here's a table summarizing the key differences:

Feature	Asset	Asset Stock	Inventory
Definition	Anything a company owns with economic value	Group of identical, long-life items	Raw materials, work-in-progress, or finished products
Examples	Buildings, machinery, vehicles, patents	Office furniture, tools, cables	Raw materials, components, finished goods
Tracking	Individual or grouped	Grouped	Individual
Lifespan	Long-term	Long-term	Short-term (expected to be sold/used within a year)
Purpose	Used for operations or holds intangible value	Used for operations	Sold or consumed in production

Why Maintenance Needs to Distinguish Between Assets, Asset Stock, and Inventory

A well-functioning maintenance department may oversee all three of these. Understanding the distinction between these categories can affect overall operations.

• Prioritization and Resource Allocation. Maintenance needs differ for each category. For example, certain pieces of machinery often require unique preventive maintenance schedules. Asset stock might need periodic replacements based on usage patterns. Inventory might need specific storage conditions to prevent spoilage. By understanding the category, maintenance can prioritize tasks and allocate resources effectively.
• Cost Management. Asset and asset stock have a longer lifespan and higher individual value compared to inventory. Maintenance needs to track costs associated with repairs and replacements for each category to ensure efficient use of the budget.
• Compliance. Certain regulations might require specific maintenance practices for particular asset types. For example, safety regulations mandate regular inspections of machinery.
• Improved Decision-Making. You should understand the health and performance of each category. With this knowledge, you shape and refine tasks and schedules for preventive maintenance (PM), general and emergency repairs, and replacements.

As you can see, maintenance certainly has an impact on the physical items. What about those non-tangible assets? Let's use a scenario for brand reputation.

A reactive mindset or poor-quality maintenance results in increased unplanned downtime. Stockouts on certain parts also delay maintenance. That downtime delays production. Those instances accumulate.

In the end, you have delayed product delivery and customer dissatisfaction. The brand reputation suffers.

Common Challenges in Defining Assets and Inventory

Despite the clear distinctions, you might have instances distinguishing those differences.

• Gray Areas. Some items might blur the lines. For instance, you might have spare parts workers consider either inventory (if readily available for sale) or an asset (if reserved for specific equipment).
• Dynamic Nature of Inventory. Inventory levels fluctuate constantly. You might have concerns with keeping track of the exact quantity of specific items at any given time.
• Lack of Clear Definitions. Companies might have different internal definitions for these categories. This leads to confusion and inconsistency in how maintenance tracks and conducts repairs on them.

Industry Examples: Highlighting the Differences

We've looked at a "big picture" discussion. Let's narrow the focus and show three industry-specific examples of each category.

Manufacturing

Asset: A factory's production line machinery.

Asset Stock: A set of wrenches used by assembly line workers.

Inventory: Raw materials like steel sheets, partially assembled components, and finished cars.

Retail

Asset: The store building and its security system.

Asset Stock: Shopping carts and display shelves.

Inventory: Clothing, electronics, and other merchandise for sale.

Healthcare

Asset: Medical imaging equipment like MRI machines.

Asset Stock: Bandages, syringes, and other medical supplies.

Inventory: Pharmaceuticals and medical devices.

How CMMS Software Helps Manage Assets and Inventory Efficiently

How can a CMMS show itself as a valuable tool for maintenance departments in understanding and managing assets, asset stock, and inventory?

• Centralized Database. A CMMS provides a central platform to store and manage data on all three categories. This includes detailed information like item descriptions, serial numbers, purchase dates, maintenance history, and location. This centralized database eliminates the need for spreadsheets or scattered paper records. System users have access to accurate, up-to-date information.
• Improved Categorization. CMMS allows for the creation of customized categories and subcategories for each. This enables clear differentiation between the types of items your organization manages. You can define specific criteria for each category. Tracking items based on purpose, lifespan, and value produces better efficiency.
• Inventory Management Features. Many CMMS offer built-in inventory management functionalities. These features allow for tracking inventory levels, setting reorder points, and generating automated purchase orders.
• Preventive Maintenance Scheduling. CMMS software helps schedule preventive maintenance tasks. In turn, you base these schedules based on manufacturer recommendations, usage data, and historical maintenance records. This minimizes the risk of breakdowns and extends the lifespan of valuable equipment.
• Work Order Management. The software processes work requests and organizes the creation of work orders for repairs. Within these orders, you can specify the type of asset or asset stock technicians need to repair. Add the required parts from inventory. Assign maintenance personnel. This improves communication and accountability within the maintenance department.
• Reporting and Analytics. Generate key performance indicator reports. Other reports include inventory costs, asset failures, and depreciation values.

Understanding the Nuances Creates Efficiency

Take time to understand the differences between assets, asset stock, and inventory. This knowledge helps improve an existing maintenance strategy.

A CMMS plays a crucial role in this process by organizing all your tasks, what assets you tend to, and the inventory used. You want to improve your return on investment (ROI) for your assets. Proper use of a CMMS will do that.
