What's wrong - and right - with this picture?
This is a real-world example (found in the wild) of how the simplest of things (in this case, a misunderstanding of roleplaying) can lay waste to a multi-million-dollar project. The problem as found is illustrated and annotated, as is the solution. Let me know if you can solve the puzzle and-or have ever run into a similar scenario.
