Waste in lean is any consumption of resources which does not benefit the customer. The Seven Wastes of lean are defects, overproduction, transport, waiting, inventory, motion, and processing. The mnemonics are DOTWIMP or TIM WOOD (includes Overprocessing rather than Processing). An Eighth Waste has been added: the waste of human potential. Time taken in wasteful activity is called non value added time i.e. time spent which adds no value for the customer.
