Some exceptional cases for narration: Social/behavioral sciences when observing patients Law enforcement/law practice when dealing with eyewitnesses or participants in events
The most important part to ANY narrative is always the conflict/problem
Once this is introduced, the details that follow will help resolve the conflict and rise to a climax that will determine the outcome of the story then it ends by the resolution it has come to (or not--sometimes stories stop unresolved and are resumed later)
