One of the most important principles may be to produce a product without defects, where each part of the product is examined after manufacturing. In this way, any defects detected can be corrected or eliminated at the earliest possible stage instead of reaching to the final stage and going over the whole process from the beginning. The final product can therefore be kept perfect and flawless. Avoiding all activities and materials that do not add value to the final product is also very important, which in turn requires to be replaced by the optimum use of valuable resources such as manpower, capital and land.

Giving value and importance to the workers and all the people involved in the production can also make a lot of difference. Workers are the people who are closest to the product and thus, their opinions and decisions regarding the betterment of the product can add a lot of value to it. Hence, their inputs need to be valued and considered as important and necessary. Manufacturers also need to be constantly improving themselves and remain flexible in their production depending on the market demands. Maintaining a healthy relationship with the suppliers can help in analyzing market rates, demands and risks involved and in the process result in more productive outcomes.

Implementing and regular following of these principles would lead to a flawless product that would automatically attract consumers and gain their preference. The best products are considered to be those, which are pulled by the consumer end and not pushed from the production end. The principles of lean manufacturing are designed to meet this criterion containing the secrets of a successful production cycle.
