Lean is all about creating the right value for customers with minimum effort!
The 5 Lean principles are:
1. Define value seen from the customers/markets point of view.
2. Identify the value stream (activities) that delivers the value defined in point 1.
3. Create flow in the value stream.
4. Create pull (order driven) in the value stream.
5. Create a culture of continuous improvement (Kaizen) in the organisation.
