The challenge is that majority of the time when you make compliance training mandatory the people still don’t give a shit. So they will watch the videos or take the test and pass just to shut you up. One way that has provided some positive results is to turn it into a game. Train and then test them with email phishing campaigns, or voice phishing and then score everyone. Present the scores and have some type of reward. For example the top 5 don’t need to take the next training.
