Continuous improvement (kaizen)
Workers in lean systems have greater responsibility for quality, and they are expected to be involved in problem solving and continuous improvement. 1.

Everyone should be involved 4. Kaizen is built on a cheap strategy, and it does not require spending great sums on technology or consultants 5. It can be applied everywhere 6. It is supported by a visual system 7. It focuses attention where value is created 8. It is process oriented 9. It stresses that the main effort for improvement should come from new thinking and a new work style 10. The essence of organizational learning is to learn while doing
