What is Continual Improvement?
Continual improvement is a recurring activity to enhance performance. It's a fundamental concept in ISO management system standards and essential for long-term success and competitiveness.
Unlike continuous improvement (ongoing), continual improvement occurs through repeated cycles of evaluation and action.
