To create interactive quizzes or activities to engage employees during training sessions on 'Risk-Based Thinking' in ISO 9001:2015, you can integrate various methods such as:

1. **Games and Simulations**: Develop games that simulate real-life scenarios where employees must identify and manage risks. This can help them understand the practical application of risk-based thinking.

2. **Quizzes and Surveys**: Conduct quizzes that test employees' understanding of risk-based concepts. Use tools like Kahoot or Quizlet to make these quizzes interactive and fun.

3. **Role-Playing**: Organize role-playing activities where employees act out different roles within a process and identify potential risks and opportunities.

4. **Case Studies**: Present case studies of past projects or hypothetical situations and ask employees to identify risks and propose mitigation strategies.

5. **Group Discussions and Brainstorming**: Facilitate group discussions or brainstorming sessions where employees can share their thoughts on potential risks in their areas and collaborate on solutions.

6. **Interactive Workshops**: Conduct workshops where employees can work in teams to map processes, identify risks, and develop action plans.

These methods can help employees internalize the concepts of risk-based thinking and apply them effectively in their daily work.
