OVERPRODUCTION
VS
OVERPROCESSING
Sugeng Endarsiwi (Printing & Ink Advisor)

• Overproduction: The act of producing more than is needed, before it is needed, and faster than is necessary.
Overproduction is by far the most common type of waste in an organization, and it can breed other wastes.
• Overprocessing: This occurs when it is hard to see when something is complete. For instance, grinding, sanding,
and polishing can be overdone, because a sense of completion is hard to gauge from one person to the next.
Redundant effort or steps, and excessive checking and verifying, are examples of overprocessing. If operators need to
unpackage parts from suppliers on the production line before installing those parts, they are overprocessing.
