Learn in the textbookPractical Methods for Idea Generation and Validation
DefinitionLean startup (リーンスタートアップ) is a method that grows a business by quickly building a minimal product, checking customer reactions, learning from them and improving, in a cycle repeated in short loops.
ExplanationThe first prototype released is called an MVP (Minimum Viable Product), and it has only the features needed to test the hypothesis. The process is a loop of build, measure and learn, and depending on what you learn, you may change the direction of the business sharply. Compared with polishing a product before launch, it avoids spending time and money on development that misses the mark.
AnalogyIt is like a food stall that offers a small batch of a different trial dish each day, then changes the flavor or menu the next day based on sales and customer comments.
Memory hookLean means "without fat, without waste", reflecting an attitude of cutting out unnecessary polishing.
