With combined annual sales of approximately $17 billion and over 2,200 retail stores across 59 countries, Office Depot is a leading global provider of workplace products, solutions and services. Until recently, however, Office Depot was facing two main challenges in meeting this high demand – low service level for highly desirable products, and too much trapped and excess inventory. The company suspected that its distribution system, called Just In Time Allocation (JITA), was the root cause of these issues. It also believed that its ABC classification system (the system responsible for classifying SKUs optimally for allocation) was amplifying the problem by not considering all major factors and objectives. Office Depot hired Optym to review its current methods and identify areas for improvement.
