Lean Principles

The main principles of Lean are:

• 
  Focus on customer needs – Prioritizing value as defined by the customer.
• Pull system – Producing on demand rather than using a "Push" system.
• Waste elimination – Removing waste at every stage of the process.
• Visual management – Using visual tools to manage and monitor processes.
• Continuous improvement (Kaizen) – Constantly seeking ways to improve processes.

These principles form the foundation of sustainable and flexible production systems.
