Ries’ book is well known in start-up scene. For a computer scientist/software engineer, the idea of the book resonates well with the agile software development movement. Ries pushes (start-up) companies to iterate the core product offering and business model of the company continuously through build-measure-learn loops and pivoting. The idea is to develop good measurements of success and continuously check how you are doing by them. Although Ries advocates rapid development, his process of continuous innovation through iterations is actually quite heavy. The process of creating hypotheses and validating them with tests is quite near the basic scientific method and requires a lot of work. Well, who said that entrepreneurship is easy.
Interestingly, Ries also claims that while start-up companies are very different from large established companies, the innovation or new product development activities of large companies are near the activities of start-up companies and that lean startup ideology can be utilized in them too.
