Types of Waste (Muda)

Lean identifies the following types of waste that reduce efficiency:

  1. Overproduction
  2. Unnecessary motion
  3. Waiting
  4. Excess inventory
  5. Defects
  6. Unnecessary transportation
  7. Unnecessary storage
  8. Underutilized employee potential

The goal of Lean is to eliminate these wastes, leading to improved quality and reduced costs.
