We used to think 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 must be subordinated to a clear methodology that has strictly defined steps. The main idea of the "economical startup" method, developed by Eric Rice, is to quickly test the ideas of new products on real consumers and constantly adjust the business model in order to start large-scale investments only when the idea is confirmed by facts. Who has already become acquainted with this book, speaks of it like this: if you are an entrepreneur, immediately throw all the cases, sit down and read! And do not be embarrassed by the words "business from scratch" in the title. Entrepreneurs are in the spirit of different companies, and be able to constantly analyze the business model and make timely adjustments to it for any business - small and large.
