Lean thinking is a management philosophy that focuses on eliminating waste and maximizing value for customers. It originated from the Toyota Production System (TPS) and has since been adopted by businesses across various industries.
Key Principles of Lean Thinking:
- Identify Value: Define what truly creates value for the customer.
- Map the Value Stream: Visualize the entire process of delivering value, identifying all activities involved.
- Create Flow: Eliminate interruptions and delays in the value stream to create a smooth flow of work.
- Establish Pull: Produce goods or services only when they are needed, avoiding unnecessary inventory.
- Seek Perfection: Continuously strive to improve processes and eliminate waste.
Examples of Waste in Lean Thinking:
- Overproduction: Making more than what is needed.

- Motion: Unnecessary movement of people or materials.
- Waiting: Time spent waiting for processes to be completed.
- Transportation: Moving materials or products unnecessarily.
