For example in a story where :
Story goal is Future - Some people trapped in a haunted house, need to find the exit to survive
Requirements: How things are changing - [What to use here]
All examples I can think of seem to be more to do with Understanding, or Doing. For example, people trying to figure out what is going on or why things are happening (seem more like understanding).
Apologies if this post makes no grammatic sense - a little sleep deprived at the moment
