By implementing a robust SKU system, businesses can gain greater control over their inventory and maintenance operations, leading to improved financial performance and reduced risk.
How Stock Keeping Unit (SKU) Works
The process of implementing and using Stock Keeping Units (SKUs) involves several key steps, starting with defining a consistent and logical naming convention. The SKU should be constructed to include relevant product attributes, such as manufacturer, model, size, color, and any other distinguishing features. This ensures that the SKU provides a clear and concise description of the item, enabling easy identification and differentiation from similar products.
Once the naming convention is established, each unique item in the inventory must be assigned a SKU. This process should be carefully documented to ensure accuracy and consistency. It is important to avoid duplicate SKUs and to maintain a central repository of all SKUs and their corresponding descriptions. This repository serves as a reference point for all users and helps to prevent errors and inconsistencies.
After SKUs are assigned, they can be used to track inventory levels, monitor consumption patterns, and manage reordering processes. Inventory management systems, including CMMS solutions, use SKUs to track the movement of items in and out of the warehouse or storage facility. When a part is used for maintenance, the corresponding SKU is updated in the system to reflect the reduction in inventory. Similarly, when new parts are received, the inventory is updated with the appropriate SKU and quantity.
SKUs also play a crucial role in generating reports and analyzing inventory data. By tracking the usage of specific SKUs over time, maintenance teams can identify trends, forecast future demand, and optimize stock levels. This data can be used to make informed decisions about procurement, resource allocation, and maintenance planning. In addition, SKUs can be used to track the cost of specific parts and components, providing valuable insights into the overall cost of maintenance and asset ownership. This information can be used to identify areas for cost reduction and to improve the return on investment for maintenance activities. Regular audits and reviews of the SKU system are essential to ensure its accuracy and effectiveness. This includes verifying that all SKUs are correctly assigned and that the inventory data is up-to-date and consistent.
