Loss Management

7 Wastes overproduction: producing more, sooner and faster than required by the next process excess transportation: any transport that adds cost but no value to the product excess inventory: this not only is a waste, but also creates waste excess processing: doing more work than necessary waiting: operator or machine idle time correction: repairs to products motion: walking or wasted motion to pick up or store parts.
