Though they sell the same product, some companies are successful, others are not

If you sell different things, it is natural that some companies are profitable and some are not. But why is it that, even though some companies sell the same products, only some are successful?

The idea is that they sell the same things, but they do things differently. In other words, management and management methods are different. To put it plainly, the way of working and the way of thinking are different. This book will focus on that way of working and thinking.
