What is Lean Manufacturing?

Lean manufacturing is an approach to production that focuses on eliminating waste and maximizing efficiency. This approach has been widely adopted by manufacturing companies around the world due to its numerous benefits. Lean manufacturing helps to streamline processes and reduce costs, while also improving quality, safety, and customer satisfaction. In this blog, we will explore the definition of lean manufacturing and the benefits it brings to companies.

Definition of Lean Manufacturing

Lean manufacturing is a process that focuses on reducing waste and increasing efficiency in the production process. It is based on the premise that eliminating anything that does not add value to the product or service will improve the overall quality, production speed and cost of the product. Lean manufacturing focuses on streamlining processes, eliminating waste, and improving the flow of materials and information. It also emphasizes team collaboration, continuous improvement and employee engagement.

The Five Principles of Lean Process Management

Lean manufacturing processes have 5 basic principles. These are as follows:

  1. Customer Value: The first principle of Lean Process Management is to determine value from the customer’s perspective. The aim is to understand what the customer wants and needs and to focus on creating value for them.
  2. Value Stream: The second principle of Lean Process Management is to map the value stream. This includes understanding the process and identifying the steps and activities necessary to create the value the customer is seeking.
  3. Flow: The third principle is to create flow. This includes ensuring that the process is efficient and that activities are performed in the correct order.
  4. Pull: This principle includes ensuring that only necessary activities are carried out and that resources are not wasted. It creates a system that allows the customer to “pull” a product or service when they need it.
  5. Perfection: The last principle of Lean Process Management is to pursue perfection. This includes continuous improvement and striving for excellence. It is important to identify areas for improvement and make changes that will lead to better results.

8 Wastes of Lean Manufacturing

Eliminating waste is not just about reducing costs. It’s also about efficiency and customer value. Waste is divided into eight different types to make it easier to identify.

  1. Inventory: Storing products before customers need them, wastes inventory.
  2. Waiting: There are unnecessary delays in production processes in case of lack of materials, information or employees. This results in the waste of waiting.
  3. Over-processing: Overprocessing waste occurs when features, materials, or extra effort are added to products that do not add value and are not needed by the customer.
  4. Over Production: Producing more than demand and what is needed causes waste.
  5. Transport: It involves the unnecessary moving of materials or equipment.
  6. Unnecessary Movement: Unnecessary movement and walking of people creates a waste of movement.
  7. Defect: Products that do not meet customer expectations are deemed defective and cause waste.
  8. Human Potential: Waste occurs when people’s knowledge and skills are not used to their full potential.

What are the Benefits of Lean Manufacturing?

There are many benefits to be gained by most companies that successfully implement the lean manufacturing approach, such as reducing waste, preventing profitability, and increasing efficiency.

  • The quality of products and services increases.
  • Efficiency increases and costs decrease.
  • It facilitates the transition of production from one product to another, enabling better response to customer demand.
  • Eliminates production waste.
  • It enables employees to take ownership of their work and take responsibility. This positively affects employee engagement.
  • Increases customer satisfaction as it provides customer-oriented production.
