Zagu o sagase : Saikyō no burando o tsukuru tameni (Tankobon Softcover)

The concept is so clear and memorable, but I'm curious whether it came from personal experience or specific case studies. How did the author develop this core analogy?

Some examples seemed geared toward big brands with massive resources. Do readers think these ideas can be scaled down for smaller teams trying to stand out in crowded markets?
