Management systems benefits

Answer: I'd say the best way is by examples. In general, the benefits of management systems are related to:
- Enhanced competitive edge
- Reduction on losses due to security incidents
- Reduction on fines due to legal or contractual non conformity
- Improvement of internal organization

So, the point is to identify for each organization examples that can be related to their context, so it will be easier for the employees and management to figure out the benefits on adopting a management system culture.
