Basic principles of Lean – Sigma . Another term is an attempt to pass reforms and reduce the variety of waste that exist in a company’s products improve the quality of goods or services that will be worth more in the eyes of the customer . Basic concepts of Lean – Sigma is ultimately lower costs incurred in the activities of the company . In this case the company concentrates identify costs that should not be issued . In other words, saving is done by emphasizing both the working efficiency realized by the member firms or not .

As anticipated that the implementation of lean manufacturing was first introduced by Taiichi Ohno of Toyota Motor Company , a world giant company that is always active in improvement and make innovations in the field of efficiency and product quality . With conditions such company Toyota to compete in the world market with the quality and competitive price .

Many companies are following in the footsteps of Toyota to improve efficiency in all sectors with lean manufacturing methods and the lean six sigma . One feature of the company is implementing lean manufacturing concepts including:

  • Speed ​​production arranged according to customer demand , is no longer based on cycle time but by the time required to complete the requested quantity customer . This would mean the production run with high efficiency
  • Perform pull production system that is doing if requested by the customer . In other words do the production as much as the customer requested so that there is no stock of goods piled up in warehouses and not absorbed by the market .
  • Avoid WIP material / semi-finished goods by production units – per unit , with the intention of accumulation of goods that will not wait for the production process .


One of the main characteristics of the companies that apply the concept of lean manufacturing is increasing the speed of production and the loss of existing waste in the company , such as : inventory , overproduction , waiting time of transport , over-process , defect and rework and movements are not required .

Methodology that is widely used in solving the problem is based on the concept of Six Sigma DMAIC ( Define -Measure – Analyze – Improve – Control ) . Any issues identified as containing waste must be solved systematically and logically . The data obtained were analyzed statistically .

The end goal of the application of Lean – Sigma is helping companies to better compete in the global marketplace . Produce higher quality products and services primarily to customers respond best (better , cheaper products , faster )
