Lean manufacturing is one of the most-successful ways to eliminate waste and increase productivity at your company. There are several lean manufacturing methodologies available, here are some of the most popular:
The 5 "S" approach was designed by the Japanese to organize the workplace and eliminate wastes. The 5 "S" approach stands for:
The 5 "S" approach is a visual method that is used for manufacturing processes down to clerical duties. The first phase entails getting rid of things you don't need. You will simply sift through your desk and keep only what is necessary to perform your job. The sorting phase is designed to simplify your desk and create a place for everything. If you have ever seen a tool board with pictures of the tools that are missing, this is an example of Seiton. Sweeping is used to keep everything clean. When the office is disorganized, it is harder for people to properly perform their job duties; cleanliness helps to remove the clutter. Sustain simply means you need to implement the program company-wide. Self-discipline implies that everyone at the company will continue to follow the program.
Kanban is commonly used as a part of the 5 "S" approach. Kanban is a method of using visual controls to maintain production levels according to customer demand. Kanban is commonly known as a pull method. To understand this, here is a small example of how Kanban is used.
You go to the vending machine and purchase a candy bar, immediately another candy bar is pushed to the row to replace it. This "message" is used to tell the vending machine it is out of stock of the candy bar and it needs to be replaced.

Kaizen is another approach that is used to increase productivity within a company by eliminating waste. The Kaizen approach uses 5 different methods to achieve its purpose:
Value stream mapping
Value stream mapping is typically used with other lean manufacturing processes like Kaizen. The goal is to identity opportunities to improve your product or service and increase your lead time.

The map will help you fix the way your production flows and help you find ways to properly implement changes for the future.
