It is a challenge to find your way around a hedge maze at ground level. Present a bird’s eye view of the maze and even a toddler can scrawl out the most efficient route. Maps work for the same reason.
From the snapshots of an office floor, it is hard to discern what a company does. A process flow diagram is way more effective.
If you opened a book and read a couple of pages at random, it is hard to decipher what the book is about. A table of contents works much better.
Bird’s eye views come in various shapes and forms. If you find yourself lost in the details, just take a step back and sketch one out.
