A general perspective is that compliance training like Good Manufacturing Practices (GMPs) must be serious. The reality is that we are all human, and we learn well when we feel open-minded and even better when we are having fun.
Whenever I talk about creating a fun learning environment, I remember a specific moment in my corporate career as a plant hygienist. I was walking with our corporate food safety specialist along the periphery of a building to check for gaps or holes that would allow pests to infiltrate the production area.
