Wall of love for Goodreads

Nowadays, this book is a classic, very insightful, no further words needed. A must read for entrepreneurs and intrapreneurs but also for people looking for new ways to be productive and avoid waste while starting new projects.

The Lean Startup is a revolutionary book. It’s talking about how to start a startup faster, smarter and efficiently. With feedback loops and early MVP you can test the product and optimize it much faster so you can build better product, faster and spend much less money in the process. The author gives another great ideas regarding to managing the development of a product and I definitely recommend this book to anyone that inspires to start a startup.

I'm planning to read it again in order to write a detailed review because the book deserves more than one read. for now my advise to you is that if you're planning a career in business, entrepreneurship or to launch a startup and you still didn't read it, hurry up because you've already missing a lot!

Interesting book. Key takeaways: - validate your assumptions as fast as possible, e.g. if the problem we are trying to solve is really a problem for our customers, - do not focus only on vanity metrics (like number of sales, new users, etc.) but identify your companies growth-engine and focus on it, - the main goal for a start-up should be to learn and innovate, - experiment, measure, adapt as you go, pivot if needed

The first book I've read on startups/business, and I think it was a great introduction. Ries' primary thesis in the book is that the process of building products and services in an environment of uncertainty (i.e. in a startup) should follow the scientific method. He argues that while most startup founders have a vision, they don't necessarily know what the customers want. The customers also don't know what they want (until you present them with something). In order to resolve this uncertainty, a startup should conduct a number of experiments with a clearly stated hypothesis. These experiments often involve a minimum viable product (i.e. the simplest product you can build that to test your hypothesis). Often, the MVP is not actually a product, but just an ad for the product (for example, to gauge potential customer interest). Validated learnings from this experiment should then drive the next set of experiments, until you reach a point where you can build a viable business around your vision. Later parts of the book deal more with late-stage startups or how to have startup teams in big companies, and I found them less interesting.

A startup is characterized by the fact that it doesn't cater to an existing market, rather it *creates* a new market with its product. There is no existing customer profile to mould your marketing strategy on, so traditional marketing and business thinking does not fare well in a startup scenario. "Lean Startup" philosophy, inspired by the Toyota production system, is a lighthouse to guide the entrepreneur in his forays into uncharted territory. This philosophy propagates such radical actions as releasing a limited functionality product to a small consumer base, at the risk of its extant brand value or future brand prospects, and surveying the ensuing feedback to build and streamline the final product. Instead of manufacturing a technically fabulous product and trying to convince the customer of its merit, the Lean Startup sets up a feedback loop between the customer and the engineering team where the customer is teased with elementary prototypes while his/her usage behaviour tells the developers the exact features required to make a product that customers would want to buy. In other words, product development is no longer the work of a visionary but a synergy between the manufacturer and the consumer. This is but a tip of the iceberg. The Lean Startup philosophy closely emulates the scientific method in formulating experiments to test business hyopotheses and using the data to either refine or reject the hypotheses in favour of new ones. The startup scenario in a fast changing world calls for new ways of business thinking, and the Lean Startup philosophy is one shot at the challenge.

I just had to give this one 5 stars, no way around it. It has some very interesting stuff in it, which makes you re-think your views on how a product needs to be built, any product which involves uncertainty. I will have to give this multiple reads to dig out the relevant details from it, and I suggest you try it sometime as well, and then let me know what you think.

In my opionion a must read for anyone working in any type of industry. Parapharsing the author: "We leave in times when we can build anything we can think of, the question is what to build".

Much better book than I expected. Eric explains his mindset and his approach to product development and how to run a start-up, and he makes TOTAL sense. I thought I knew concepts like validated learning & continuous deployment, but reading through this book really solidifies these ideas in my head. These insights are really impressive and I'm hoping I can apply some of the ideas in my next startup.

Best book for start-ups. This book does not contain many fancy you-have-a-passion-just-do-it examples like other start-up books do. I appreciate the applicability of this book and recommend it to everyone. Takeaways: 1. Start-ups should focus on management, process, and discipline, which is counterintuitive to the conventional idea that start-ups should have a 'just-do-it' attitude. 2. Start-ups should develop Build-Measure-Feedback loop. Companies should develop a MVP to test market hypotheses. A MVP (minimum value product) is a product that lacks some feature because it is developed in a short time with less effort. With MVP, start-ups can see customers' reaction to the product. Start-ups must test the riskiest assumption first. 3. Cohort analysis, which studies the behavior of independent customer segments to a product, is proven to be more meaningful than other forms of line graphs. 4. When there is a problem, entrepreneurs should ask 5 'Why?' questions (root cause analysis) in order to seek for appropriate solutions. 5. Instead of vanity metrics, investigate into actionable metrics. Vanity metrics waste your time in satisfying yourself without bringing any meaningful analysis.
