This is cool. It feels a lot like business school cases where you get a packet of context and need to think about how to navigate the many factors at play, though with more direct practice, much less of the social dynamics of a class discussion, and less of a main character storytelling vibe, which are all good things IMO.
If there was a way to combine this with coaching sessions, I think this could be a very effective way to train IC's that are stepping into leadership roles (managers, staff/principal IC's, PM's, etc.). It could also be interesting to have a variant of the exercise where you ask the student/user to write their own message.
