This module is a complete examination of a company’s safety stock levels. It starts with the reasons to keep safety stock levels, reviews how a company inventory levels match the safety stock levels set, looks at how safety stock should be calculated based on demand, supply, and process input, and reviews how safety stock should be used in both an MRP and independent demand re-order point systems.
Based on past experience with the understanding contained in this module, a company should be able to significantly reduce their inventory levels while maintaining, or improving, their customer service and operational process service levels.
Those people responsible for setting safety stock or those that are most directly affected. Attendees would need to bring safety stock level data for at least one SKU, and the class would need access to an ERP system (either online or reports).
