Program Objectives

This course will provide participants with practical techniques to generate more accurate forecasts and desired inventory levels as well as to monitor and improve forecasting and inventory management performance over time.  We will discuss what sources of information can be used to improve forecast and inventory management performance.  In addition, we will investigate the critical financial impacts that overinflated inventory levels may cause.

    Value Created for You and Your Company

    In most business contexts, forecasts are needed to support resource allocation decisions.  More accurate forecasts lead to better resource allocation and thus improved financial performance, particularly by reducing the amount of inventory that must be carried.  The direct relationship that exists between forecasting and inventory management is why this course will address both key supply chain concepts together. Inventory management may be the most important “lever” in the supply chain in its overall effect on corporate profitability.  This course is designed to strengthen understanding of the foundational concepts in forecasting and inventory management and to provide participants with the contextual knowledge of how to use these concepts to drive improvements.
