To create interactive quizzes or activities to engage employees during a training session on 'Risk-Based Thinking' in ISO 9001:2015, you can incorporate games that test topics related to ISO 9001. Use on-job training where you start with what people do, the purpose of their tasks, what can go wrong, and how ISO 9001 can help minimize errors and increase correct actions. Additionally, you can create a “fun” questionnaire to test ongoing knowledge and schedule training based on identified gaps. Engaging employees through interactive methods ensures they internalize the concepts and apply them consistently.
