What is Lean Methodology?
Lean methodology originated in manufacturing, but its principles can be extended to any business process.
The core idea is to maximize customer value while minimizing waste. Waste is any activity or process that consumes resources without creating value for the customer.
The main elements of lean methodology include:
- Identifying value from the customer’s perspective.
- Mapping the value stream and eliminating waste.
- Achieving flow in processes.
- Responding to customer pull.
- Pursuing perfection through continuous improvement.

- Use visual metrics to track performance.
- Design processes to enhance flexibility.
- Cross-train employees (e.g., sales methodologies) to increase workforce agility.
- Encourage bottom-up innovation and problem-solving.
- Foster an environment of continuous experimentation.
- Align policies and procedures to support lean practices.
- Reward and recognize employees for lean accomplishments.
Examples of Lean in Action
Here are a few examples of how lean principles have been applied by companies:
- Toyota uses Kanban cards to signal when more inventory is needed in its just-in-time system. This aligns production with actual demand.
- Apple stores enable customers to check out anywhere in the store with mobile devices, eliminating the waste of waiting in line.
- Amazon has implemented extensive automation in its fulfillment centers to optimize picking and packing processes.
- Spotify uses agile methodologies and software development methods with small cross-functional teams to frequently deliver new features.
- Nike applies lean manufacturing techniques to their apparel production to minimize defects and speed up changeovers.
