To create interactive quizzes or activities to engage employees during training sessions on 'Risk-Based Thinking' in ISO 9001:2015, you can incorporate the following strategies:

1. **Scenario-Based Quizzes**: Develop quizzes that present real-life scenarios related to risk-based thinking. Ask employees to identify potential risks and suggest actions to mitigate them.

2. **Role-Playing Activities**: Organize role-playing sessions where employees act out situations involving risk assessment and management. This helps them understand the practical application of risk-based thinking.

3. **Group Discussions**: Facilitate group discussions where employees can share their experiences and insights on identifying and managing risks in their daily work.

4. **Interactive Workshops**: Conduct workshops that involve mapping processes and identifying risks using flowcharts. Encourage employees to collaborate and propose solutions.

5. **Games and Simulations**: Use games or simulations that mimic business processes and require employees to make decisions based on risk assessments.

6. **Brainstorming Sessions**: Arrange brainstorming sessions to discuss risks and opportunities using tools like SWOT or PEST analysis.

These interactive methods can help employees internalize the concept of risk-based thinking and apply it effectively in their roles.
