Anyone can see a forest fire. Skill lies in sniffing the first smoke.Ever know enough about your job, car, plane or boat that you get that "vibe" that tells you something "bad" is about to erupt? That's why we have strategic planners peering off into the future and making all those contingency plans.
- Robert A. Heinlein
If everything happens "unexpectedly" you are not very good at your job.
