Pure product marketing

The book is a compilation of tips and illustrations (at least one illustration of a page by council). If some tips can be interesting, the authors never explain how they are effective or functional, and offer rarely concrete examples (many examples of companies that use them, without specifying how they use) .

Allow 2 hours of reading about, after which you will say without doubt that this book is ultimately nothing more than a flashy product intended to sell and make a profit.
