Inventories are materials and products waiting for processing, transport, sale or use in production and logistics systems.
Supply chain management focuses on correctly managing inventory flows within and between facilities.
The types of materials and inventories present in a supply chain can be summarized as follows:
Inventory management ensures that right materials are available in the right quantity, at the right place, at the right time and at the right cost. Inventory is one of the largest cost items for many companies. Organizations that manage inventories effectively gain competitive advantage. Poor inventory management leads to losses in cash or sales.
Excessive inventory can hide many supply chain and production problems...
Effective inventory management encompasses many approaches and activities aimed at improving an organization's competitiveness. The main objectives can be summarized as:
Holding inventory is necessary in supply chain management. In some cases inventory levels will exceed immediate need. The factors below may justify holding inventory above demand:
Companies can add many factors specific to their operations. The large number of drivers makes effective inventory management a challenging task.
Inventory segmentation groups inventory items according to criteria so that each group's characteristics and needs are better understood. Segmentation helps make more focused and effective inventory decisions.
Typical inventory segments include:
Various analysis methods help classify items and guide planning and control processes:
Combinations of these methods (e.g., ABC–XYZ) are commonly applied.
These tools enable prioritization, control level setting and efficient resource use. Inventory analysis methods are critical tools that help improve competitiveness.
Core challenges stem from uncertainties and variability on the customer and supplier sides, plus operational and capital cost issues. These challenges can be addressed by reliable forecasts and effective planning.
Service level measures the success in meeting demand; it is closely tied to inventory availability at the moment of need and directly affects sales. Hence it is an important competitiveness metric.
Inventory costs arise from purchasing, producing, storing inventory, opportunity costs and overheads.
Trade-offs between service level and inventory costs must be decided for each company.
The goal is to determine inventory levels that meet service level expectations while keeping total costs low.
Organizations must accurately compare the costs of holding versus not holding stock.
Inventory optimization adjusts stock levels to best meet the organization's needs and objectives, seeking to minimize inventory costs while maximizing service levels. Two key decisions are when and how much to replenish. Various methods and tools support these decisions:
There are common practices applicable to many companies. However, factors such as: sales, production and procurement strategies, product and process characteristics, supply chain operations and relationships, customer and supplier expectations, and assumptions about future actions are mostly company-specific, meaning that inventory optimization must be tailored per organization.
These factors require inventory management processes to be designed like tailor-made solutions for each company.

“Hello, First of all, I thought a lot about how I could enjoy another 4-day training. I was very excited about the fact that it was definitely the field I was personally interested in and the thought of integrating it into the institution I work for. Especially as you know, every institution will/should switch to the S&OP process. This course discusses end-to-end supply chain processes and the requirements of S&OP in detail. I would like to thank Dr. İlker Güçlü again for this beautiful training.”
