Lean Manufacturing Principles

Lean Manufacturing is a management method created by Toyota in Japan after World War II. It is based on optimizing production, improving productivity and quality and minimizing the time and resources needed to eliminate waste. In addition to being a customer-centric strategy, which also aims to increase the added value of products and services. This method uses multiple tools to find the most effective way to produce and use results, always seeking continuous improvement.

Principles:

In this methodology the principles are divided into 5 parts, not which they are: Value definition, Value stream, Continuous flow, Pull production and Perfection, let's now report a little about each of these principles.

• Value definition:

Value includes everything that customers consider important and that makes the purchase of a product or service effective. That's the basis of the principles, because from there you can move on to the next one, always focus on content that adds value to the customer, and try to eliminate or at least reduce content that doesn't add value.

Value stream:

The value stream map includes all necessary activities from the start of the production process to the delivery of the final product to the customer. After this mapping, these activities can be organized and prioritized to distinguish them into value-added activities and non-value-added activities.

• Continuous flow:

In order to have a faster and more efficient production, it is necessary that after defining the value and identifying and eliminating the activities that do not add value, we can establish a continuous process that organizes the process steps in a harmonious way, without interruptions and without intermediate stock.

• Pulled production:

Based on the customer's need, pull production is nothing more than producing only when requested, where the objective is to eliminate inventories and excess production.

• Perfection:

Based on all of the above principles, I must always be looking for perfection, where improvement is always continuous, and keep in mind that there is always something to be improved.
