A - Active - Keep learners active throughout the workshop. Being active might include practice, working in teams/pairs, problem solving, redesigning etc In other words, step back and make way for learning.
B - Benefits - Learners need to see the WIIFM before they decide to actively participate in the coming content. If they cannot see how the content will directly benefit them eg increased sales, hitting targets, staying safe etc they will simply switch off. So make sure you benefit sell all content from your learner's perspective.
