What does the Over-processing sign suggest?

The Over-processing sign indicates that there are additional tasks being performed beyond what is necessary to achieve the desired outcome. This typically occurs when processes are designed or executed in a way that adds unnecessary steps or complexity, which does not add value to the end product or service.

In Lean practices, over-processing is identified as a waste because it consumes time, resources, and effort without contributing to customer value. For example, if a product goes through extra review phases or if redundant paperwork is filled out, those steps can be seen as over-processing. Recognizing and eliminating such activities allow organizations to streamline their operations and focus on what truly adds value, thereby improving efficiency and reducing costs.
