Which inventory control technique involves color coding items by classification?

• A. Color coding items by classification
• B. Etching the inventory control number on the tool
• C. Using prepared spaces on a shadow board for storage
• D. Having an orderly method: laying out items in order or group them

Answer: (A)

Color coding by classification is a visual management technique in inventory control. By assigning specific colors to categories of items, workers can instantly see what class an item belongs to, how urgent it is, or what storage rules apply. This speeds up picking and counting, reduces mistakes from mixing items, and makes inspections easier. The color codes act as a quick, universal signal that’s easy to learn across shifts, helping maintain consistent organization.

Etching an inventory control number on a tool focuses on traceability and exact identification through numbers, not colors, so it doesn’t provide the at-a-glance classification that color coding offers. Prepared spaces on a shadow board organize where items go, which helps with locating tools but doesn’t use color to indicate category. Laying out items in order or grouped is about overall organization and placement, not signaling classifications with colors.
