I'm just gonna sliiide in here for a hot second, if nobody minds.
A change/stop character has an unnecessarily large impact regarding some trait and needs to lose it; in other words, they need to learn to sit down and listen. The argument is simply, “stop doing that.” On the other hand, a change/start character needs to stand and speak up; they have an unnecessarily small impact in some area and need to gain something. The argument is, roughly, “keep doing this, but also try doing that.”
Are they selling themselves short, or overextending themselves?
To use your "courage/fear" example, does the character need to remain a shrewd tactician, but also learn to risk defeat, or do they need to overcome their fear of battle, because they’re constantly disengaging?
It’s the same kind of difference for a steadfast character, but this time the problem is without themselves—e.g. in other characters. Where do their problems come from? From something others do (run away), or from something they don’t do (risk defeat)?
To be completely honest, I've never actually seen the Bourne Identity, but I'm assuming 'they' (not necessarily the bad dudes) aren't stepping up.
