What are the downsides to using stories for training and development? - Training Films You'd Watch at Home | Video Production for L&D | Sage Media
The version of storytelling apparently assumed as the basis of this article is when a trainer shares an anecdote or story with a moral during live training. While that's not generally how I use storytelling in my own work, some of the issues here are relevant to elearning and interactive storytelling too. Stories should be relevant and connect to the goals of the course. You should revise your writing to polish it (although I think the note about revising dozens of times for a movie script isn't really relevant to training--none of us have that much time for revisions, nor do we need it to be that kind of quality).
