Design for six sigma is a method or approach used in designing products and processes which attempts to create and provide products and processes that adhere or comply with six sigma quality or approximately 3.4 defects per million opportunities.
The 5 core principles of a Lean Organization were first written about in a book entitled: Lean Thinking by James P. Womack and Daniel T. Jones. The 5 core principles are widely accepted as a means implementing and establishing a lean organization. The 5 core principles have been adapted from the 5 original principles that were defined by Dr. Womack and Daniel T. Jones:
Visual management is a way to visually communicate and manage various standards, metrics, improvements, safety requirements and expectations. All forms of visual management should be clearly displayed and understood with no explanation other than visual analysis by everyone.
Value added work is the actual work that a customer is willing to pay for. It can be described as any activity that transforms a product or service from one condition to another, is done right the first time through and somebody is willing to pay for it. With that said, value added work has three defining characteristics. We’ve outlined them in a checklist below:
Here is an example of a value added activity. Keep in mind that no process is 100% free of waste. John receives an order for a part he must machine. John begins machining his part and completes it correctly the first time through. This is seen as value added because the customer is willing to pay for it, the transformation occurred on the machine and he machined the part correctly the first time through. Let’s look at one more example. Martha requests some information from Dianne. Dianne gathers the necessary information and emails Martha. When Martha receives the information she is grateful. She reads through the email and is able to get all the information she needs to complete her task. This would be considered a value added email because Martha requested it, the email contained all the necessary information and it was performed correctly the first time.
Some activities can be difficult to determine whether they are value or not. If you are unsure as to what type of work the activity should be classified as, ask yourself the three questions shown below:
If any of your answers were a no, the activity can not be value added and is either Business necessary work or non-value adding work.
John receives a second order for parts he needs to machine. He begins machining the parts however one hole is undersized. Because it is undersized he can rework the hole. Is this activity still value added?

The 5S system is a visual workplace management system that promotes safety, efficiency and teamwork while making abnormalities visible.
A dedicated line is one that is configured to run, produce or supply either information or parts one piece at a time. This allows production to move from station to station at a more rapid pace and ultimately improves quality, efficiency and eliminates waste. Dedicated lines should be established only after analysis as they often times require larger investments.
Lean is a continuous improvement strategy that a company embarks on to maximize customer value and minimize waste. The term "Lean" was first used in the book The Machine That Changed the World by James Womack. A lean organization focuses on providing complete value or Value added activities to their customers. One of the ways that lean accomplishes this is through the complete and total elimination of any form of waste.
