We are used to believing that processes and management are something boring and dull, and startups are dynamic and exciting, where there is no place for any rules. However, the opposite is true: the creation of a startup should be subject to a clear methodology that has strictly defined steps.

Who has already met this book, speaks of it like this: if you are an entrepreneur, urgently quit all business, sit down and read! And don't be confused by the words "business from scratch" in the title.
