Lean Manufacturing Transforms Businesses

The origins of the lean concept

In the middle of the 20th century, Toyota-the Japanese automaker-introduced lean manufacturing. To eliminate diverse waste types, the automaker introduced three broad categories-mura, muda and muri. (The lean principles were built from these three concepts only.)

  • Muda-it primarily refers to the seven waste forms.
  • Muri-it includes the modifications (in a production process) to get rid of the identified wastes
  • Mura-it comprises the steps that have to be taken (proactively or in response to a completed process) for eliminating unforeseen wastes

The seven waste types

Analyzing the working of lean principles begins by knowing muda (the seven waste forms) that is generally found while product manufacturing is underway.

Overproduction

This specific waste is of two types. First-if there is a manufactured product that is (or must be) sold at low rates, it can easily distress the company’s bottom line. Second-if there is a product that is manufactured before its buying needs arise, resources must be earmarked to store the merchandise.

Inventory

Having an excess of inventory requires the additional money that is spent on storing it.

Conveyance

If you will unnecessarily move a part during a manufacturing process, you are likely to damage it and delay the entire production process too.

Correction

This, by and large, refers to the correction made in a work that has already been done. By doing so, you can incur heavy costs because you will have to check the production process from the beginning.

Motion

The term “motion” consists of all the body movements that are made by a worker during the manufacturing process. Motions sometimes include the body movements that cause stress and lead to possibly injuries as well.

Processing

If you are confused about the product’s working or the wants of the customers, that confusion can result in waste generation.

Waiting

Any delay that is encountered in the manufacturing process can waste a lot of time; this can increase the worker’s downtime, too.
