The Five Principles of Lean Culture

The Five Principles of Lean Culture: Insights from “The Machine That Changed the World”

The book “The Machine That Changed the World” was written in 1996 by James Womack, Daniel Jones, and Daniel Roos. In it, the authors discovered five basic principles that are essential in creating a permanent “lean” culture. These principles, as well as their importance in the modern organizational context, were discussed above.

1. Value:

In conclusion, the center of the lean philosophy is the value, which is always determined by the needs in the relevant situations provided by the customer. Thus, the needs are the basis for any improvement work, while each process step must be concerned with meeting customer requirements.

2. Value Stream:

As soon as the customer’s requirements are grasped, the next stage involves the creation of the value stream, which is a series of steps and procedures necessary for creating the ultimate product or service . Value Stream Mapping quickly proves to be beneficial, as the VSM diagram enables one to uncover that which is of value and shine a light on that which is a waste. After having done this, companies can expunge the inefficiencies in their work.

3. Flow:

Eliminating wastes, in turn, puts a focus on creating flow within the value stream. The process steps need to flow seamlessly, without any interruptions, so that the transfer to the customer is more urgent. Overproduction is an issue that can be minimized through a pull system: each step “pulls” the previous one, ensuring that production is not done before it is required and prevents inventory build-up and downtime .

4. Pull:

Pull-based approach is a perfect exemplar of a demand- driven system approach as production starts with the order from the customer . This approach enables the alignment of the company operations to the customer demands for optimal efficiency and minimal wastage . This approach fosters a fast and flexible environment where the resource is optimally distributed based on accuracy of needs.

5. Perfection:

Perfection is the essence of lean. It is about an obsessive need for regular improvement, recalibrating through the prior steps until the state of perfection is achieved. A desire for perfection drives the entire culture which supports the organization and enables it to become more adaptable and robust.


To wrap up, the principles set forth in The Machine That Changed the World present a viable strategy for organizations which strive to develop a lean culture. By implementing a value-centered approach, improving and standardizing each process, as well as supporting constant change, enterprises can boost their productivity, maximize the use of their resources, and eventually provide unmatched value to their clients.
