Eight types of waste are defined including motion, transportation, inventory, overproduction, waiting, overprocessing, defects, and underutilization of talent. Examples of waste in both office and manufacturing settings include unnecessary movement of people and materials, excess inventory, producing more than demand requires, idle time waiting for resources, rework, and underutilizing employee skills.
