What are the 8 types of waste in lean?

Here are the 8 Wastes of Lean Manufacturing:

  • Transport. The transport waste is defined as any material movement that doesn’t directly support immediate production.
  • Inventory.
  • Motion.
  • Waiting.
  • Overproduction.
  • Over-processing.
  • Defects.
  • Unutilized talent.

What are the 7 wastes and what do they mean?

Under the lean manufacturing system, seven wastes are identified: overproduction, inventory, motion, defects, over-processing, waiting, and transport.

What is overproduction in lean?

In lean, overproduction refers to producing too much of a product or service and/or producing it before it is needed. Overproduction causes waste up-front by over-utilizing resources before the product is even procured by the customer. Overproduction in manufacturing most often leads to wastes of resources and time.

What are the 5 principles of lean?

According to Womack and Jones, there are five key lean principles: value, value stream, flow, pull, and perfection.

What are the 5S of lean?

The 5S pillars, Sort (Seiri), Set in Order (Seiton), Shine (Seiso), Standardize (Seiketsu), and Sustain (Shitsuke), provide a methodology for organizing, cleaning, developing, and sustaining a productive work environment.

How do you identify lean waste?

The Lean theory describes 7 major areas where you can identify Muda activities, more popular as the seven wastes of Lean.

  1. Transportation. This type of waste is when you move resources (materials), and the movement doesn’t add value to the product.
  2. Inventory.
  3. Motion.
  4. Waiting.
  5. Overproduction.
  6. Over-processing.
  7. Defects.

What does Mura mean in lean?

unevenness, non-uniformity, and irregularity
Mura (斑) Mura means unevenness, non-uniformity, and irregularity. Mura is the reason for the existence of any of the seven wastes. In other words, Mura drives and leads to Muda. For example, in a manufacturing line, products need to pass through several workstations during the assembly process.

What is transport waste in Lean?

The waste of transportation involves moving inventory, people, tools, or other items more often or further than is necessary. Excessive movement can lead to product damage, unnecessary work, and exhaustion. Examples of transportation waste include: Moving hospital patients from department to department.
