Although it can be tempered by degree, Success or Failure is easily determined by seeing whether or not the Objective Characters achieve what they set out to achieve at the beginning of the story.
Certainly, the Objective Characters may learn they really don’t want what they thought they did, and in the end not go for it. Even though they have grown, this is considered a Failure — they did not achieve what they originally intended.
Similarly, they may actually achieve what they wanted, and even though they find it unfulfilling or unsatisfying, it must be said they succeeded.
The point here is not to pass a value judgment on the worth of their Success or Failure, but simply to determine if the Objective Characters actually did succeed or fail in the attempt to achieve what they set out to achieve at the beginning of the story.
