2. Core Principles of Lean
Lean principles are built on a foundation of continuous improvement and respect for people. The core principles of Lean include:
Principle 1: Value
- Action: Define value from the customer’s perspective, focusing on what the customer needs and is willing to pay for.
- Example: “Identify the features and attributes of a product that are most important to customers, such as durability and performance.” Defining value helps in aligning efforts with customer needs.
Principle 2: Value Stream
- Action: Map the value stream, identifying all steps in the process and eliminating those that do not add value.
- Example: “Create a value stream map of the production process, identifying and eliminating non-value-adding steps such as excessive movement and waiting.” Mapping the value stream helps in visualizing and improving the process flow.
Principle 3: Flow
- Action: Create a smooth flow of work by ensuring that processes move seamlessly without interruptions or delays.
- Example: “Reorganize workstations and implement standardized work procedures to ensure a smooth flow of production.” Creating flow helps in reducing delays and improving efficiency.
Principle 4: Pull
- Action: Implement a pull system where work is initiated based on customer demand rather than pushing products through the process.
- Example: “Use a Kanban system to ensure that production is based on actual customer orders rather than forecasts.” Implementing pull helps in reducing inventory and aligning production with demand.
Principle 5: Perfection
- Action: Strive for perfection through continuous improvement, regularly seeking ways to enhance processes and eliminate waste.
- Example: “Engage employees in regular Kaizen events to identify and implement process improvements.” Striving for perfection helps in fostering a culture of continuous improvement.
| Principle | Description | Example Use Case |
|---|---|---|
| Value | Define value from customer’s perspective, focusing on what customer needs and is willing to pay for | Identifying features and attributes of a product that are most important to customers, such as durability and performance |
| Value Stream | Map value stream, identifying all steps in process and eliminating those that do not add value | Creating value stream map of production process, identifying and eliminating non-value-adding steps such as excessive movement and waiting |
| Flow | Create smooth flow of work by ensuring processes move seamlessly without interruptions or delays | Reorganizing workstations and implementing standardized work procedures to ensure smooth flow of production |
| Pull | Implement pull system where work is initiated based on customer demand rather than pushing products through process | Using Kanban system to ensure production is based on actual customer orders rather than forecasts |
| Perfection | Strive for perfection through continuous improvement, regularly seeking ways to enhance processes and eliminate waste | Engaging employees in regular Kaizen events to identify and implement process improvements |
The core principles of Lean focus on creating value, mapping the value stream, ensuring smooth flow, implementing pull systems, and striving for perfection through continuous improvement.
