Improving Capital Employed of Indirect Material in Stock within the Process Industry : A Case Study on the Relationship Between Working Capital Optimization and Inventory Management

Sammanfattning: It is essential for companies within the process industry to obtain sufficient inventory of indirect material to gain supply chain resilience. Yet, a capital-intensive company that lack efficient inventory management can generate high levels of tied-up capital. The aim of this thesis is to analyze how to optimize Working Capital (WC) for indirect material in stock through a singlecase study at an international mining and metals company. It consist of analytic interviews based on the Performance Management framework evaluating the performance level of WC optimization across the company’s decentralized sites. The results reveals that it is essential to combined both inventory management and WC management to reduce capital employed while maintaining sufficient inventory. For instance, this requires implementation of multi-criterion classification methods for critical items, and purchasing strategies adopted after an item’s lifecycle. Additionally, strategic actions regarding inventory visibility, monitoring and planning are required to reduce excess and dead inventory. The results confirms that information flows are required between involved departments to improve WC while meeting organizational demands. Finally, companies are facing increased uncertainty that impacts their ability to stay competitive and gain supply chain resilience. This thesis suggests ways to mitigate negative consequences from WC optimization during uncertainty.
