To create interactive quizzes or activities to engage employees during training sessions on 'Risk-Based Thinking' in ISO 9001:2015, you can incorporate games that test topics related to ISO 9001, making the learning process engaging and practical. Use scenarios where employees identify potential risks and opportunities within their work processes and discuss how to address them. You can also use tools like SWOT or PEST analysis in group activities to brainstorm risks and opportunities. Additionally, consider using flowcharts to map processes and ask employees to identify what can go wrong and how to mitigate those risks.
