What is Lean?
Lean is a
business methodology that focuses on creating value for the customer by optimizing resources, reducing waste, and improving quality. Originating from the
Toyota Production System (TPS), lean principles have been widely adopted across various industries beyond manufacturing. The core idea is to maximize customer value while minimizing resources used.
Key Principles of Lean
There are five key principles of lean: Value: Define what is valuable to the customer and focus on delivering it.
Value Stream: Map out the entire process to identify and eliminate waste.
Flow: Ensure that the workflow is smooth and uninterrupted.
Pull: Produce what is needed when it is needed, based on customer demand.
Perfection: Continuously strive for improvement in all aspects of the business.
Why is Lean Important?
Lean is important because it helps businesses become more efficient and effective. By focusing on waste reduction and continuous improvement, companies can offer better products or services at lower costs. This not only enhances customer satisfaction but also improves
profitability and competitiveness in the market.
