It's like sitting in your car's driver seat.
You know the map to get to your goal (creating and following your structure).
You know where to stop and turn to the left or right (wrapping up in between and changing to next topic of analysis).
You know when you arrived (giving your final synthesis and recommendation).
In a real-life situation you are paid for defining the process and doing the work to come to a solid conclusion of a given client's issue. The client won't guide you step-by-step because he doesn't know it, that is why he hired you in the first place.
