Lean Manufacturing , or also known as the Lean Enterprise , Lean Production , or simply just called ” Lean ” it is a methodology that focuses on the use of production practices and empowering resources to create value for customers ; way is by eliminating waste ( waste ) that occurs the process so that the process is more effective and efficient , with better output quality .
In the eyes of the customer , ” value” as used here means all the factors that make customers willing to buy or pay for a product or service .
In essence , Lean focused on ” preserving value with less work” .
Fundamentally , Lean has focused on how to maximize the organization’s value ( value ) received by the customer and at the same time minimizing waste in the process . Waste ( waste ) is a process that does not provide value ( value) to customers .
This concept was originally applied by Toyota in its production process . Researchers from MIT who wrote about the concept in the book ” The Machine That Changed The World ” introduces istilan ” Lean ” which refers to the concept . Afterwards, the term Lean is known throughout the world .

The basic principle of Lean is :
1. Give VALUE according to the needs and demands of customers .
2. VALUE STREAM identification for each product / service .
3. Create a process flow into a routine and continuous phases ( continuous FLOW ) .
4. Apply a pull system (pull systems ) in the process .
5. Do consistently to achieve the perfect ( ZERO – WASTE ) .

What should be emphasized before the start of Lean initiatives in the organization is that Lean is not an instant improvement program . It takes a sustained effort to improve the results of the application of Lean in the organization . Lean should be run regularly and intact , and should be part of the corporate culture .
In Lean conception indeed there are many tools that are used to repair , such as 5S , Kanban , QCC and so on . Many organizations do not want to bother and just apply the tools separately . Is it ideal ? In the eyes of Lean , it is far from ideal . Such organizations will likely fail to gain huge profits from the application of Lean .
