What are the seven 'wasteful' activities that 'Lean Manufacturing' and 'Just-in-Time Manufacturing' attempt to eliminate?

 
  • mistakes and defects that require rectification
  • over-production of unwanted products (products for which there is no immediate requirement)
  • in-process inventories (i.e. work-in-progress)
  • processing steps that aren't actually needed
  • unnecessary movements of people and goods
  • waiting for equipment or up-stream processes
  • poor design of goods and services

Lean Manufacturing and Just-in-Time Manufacturing involve the removal of all unnecessary costs. Waste elimination is translated into customer satisfaction (improved performance, quality, cost, delivery, etc).
