[Book 27] The Lean Startup by Eric Ries

The Lean Startup outlines an entrepreneurial methodology for transforming new ideas into successful business outcomes, and is applicable to companies of any size and in any industry. Business cases are built on two foundational assumptions: the value and growth hypotheses. The value hypothesis demonstrates how your product or service creates value for both the consumer and your business, while the growth hypothesis outlines the pathway for adoption. Eric introduces validated learning as a progress metric that focuses on evidence-backed insights to either support or redirect your hypotheses. This approach helps you discover value, use it to iterate your business case, and avoids waste from executing the wrong ideas. This book has helped me distill the value in my business cases, which has sped up iteration and boosted confidence in successful outcomes.

You should read this book if you…

• want advice on how to transform ideas into products and/or services
• seek to increase the speed and efficiency of your learning
• need help scaling your products and/or services

Key Highlights

1. Entrepreneurs are everywhere. You don’t have to work in a garage to be in a startup. The concept of entrepreneurship includes anyone who works within my definition of a startup: a human institution designed to create new products and services under conditions of extreme uncertainty. That means entrepreneurs are everywhere and the Lean Startup approach can work in any size company, even a very large enterprise, in any sector or industry
2. The Lean Startup method, in contrast, is designed to teach you how to drive a startup. Instead of making complex plans that are based on a lot of assumptions, you can make constant adjustments with a steering wheel called the Build-Measure-Learn feedback loop. Through this process of steering, we can learn when and if it’s time to make a sharp turn called a pivot or whether we should persevere along our current path. Once we have an engine that’s revved up, the Lean Startup offers methods to scale and grow the business with maximum acceleration
3. Products change constantly through the process of optimization, what I call tuning the engine. Less frequently, the strategy may have to change (called a pivot). However, the overarching vision rarely changes. Entrepreneurs are committed to seeing the startup through to that destination. Every setback is an opportunity for learning how to get where they want to go
4. We adopted the view that our job was to find a synthesis between our vision and what customers would accept; it wasn’t to capitulate to what customers thought they wanted or to tell customers what they ought to want
5. “Traditionally, the product manager says, ‘I just want this.’ In response, the engineer says, ‘I’m going to build it.’ Instead, I try to push my team to first answer four questions: 1. Do consumers recognize that they have the problem you are trying to solve? 2. If there was a solution, would they buy it? 3. Would they buy it from us? 4. Can we build a solution for that problem?”
6. “Success is not delivering a feature; success is learning how to solve the customer’s problem.”
7. To apply the scientific method to a startup, we need to identify which hypotheses to test. I call the riskiest elements of a startup’s plan, the parts on which everything depends, leap-of-faith assumptions. The two most important assumptions are the value hypothesis and the growth hypothesis. These give rise to tuning variables that control a startup’s engine of growth. Each iteration of a startup is an attempt to rev this engine to see if it will turn. Once it is running, the process repeats, shifting into higher and higher gears
8. The goal of such early contact with customers is not to gain definitive answers. Instead, it is to clarify at a basic, coarse level that we understand our potential customer and what problems they have. With that understanding, we can craft a customer archetype, a brief document that seeks to humanize the proposed target customer. This archetype is an essential guide for product development and ensures that the daily prioritization decisions that every product team must make are aligned with the customer to whom the company aims to appeal
9. In fact, I have often given entrepreneurs fearful of this issue the following assignment: take one of your ideas (one of your lesser insights, perhaps), find the name of the relevant product manager at an established company who has responsibility for that area, and try to get that company to steal your idea. Call them up, write them a memo, send them a press release—go ahead, try it. The truth is that most managers in most companies are already overwhelmed with good ideas. Their challenge lies in prioritization and execution, and it is those challenges that give a startup hope of surviving
10. Innovation accounting works in three steps: first, use a minimum viable product to establish real data on where the company is right now. Without a clear-eyed picture of your current status—no matter how far from the goal you may be—you cannot begin to track your progress. Second, startups must attempt to tune the engine from the baseline toward the ideal. This may take many attempts. After the startup has made all the micro changes and product optimizations it can to move its baseline toward the ideal, the company reaches a decision point. That is the third step: pivot or persevere. If the company is making good progress toward the ideal, that means it’s learning appropriately and using that learning effectively, in which case it makes sense to continue. If not, the management team eventually must conclude that its current product strategy is flawed and needs a serious change. When a company pivots, it starts the process all over again, reestablishing a new baseline and then tuning the engine from there. The sign of a successful pivot is that these engine-tuning activities are more productive after the pivot than before
11. When one is choosing among the many assumptions in a business plan, it makes sense to test the riskiest assumptions first. If you can’t find a way to mitigate these risks toward the ideal that is required for a sustainable business, there is no point in testing the others
12. Why does stuffing one envelope at a time get the job done faster even though it seems like it would be slower? Because our intuition doesn’t take into account the extra time required to sort, stack, and move around the large piles of half-complete envelopes when it’s done the other way.2 It seems more efficient to repeat the same task over and over, in part because we expect that we will get better at this simple task the more we do it. Unfortunately, in process-oriented work like this, individual performance is not nearly as important as the overall performance of the system
13. Sustainable growth is characterized by one simple rule: New customers come from the actions of past customers
14. Startups occasionally ask me to help them evaluate whether they have achieved product/market fit. It’s easy to answer: if you are asking, you’re not there yet
15. I ask teams to adopt these simple rules: 1. Be tolerant of all mistakes the first time. 2. Never allow the same mistake to be made twice
16. We often frame internal innovation challenges by asking, How can we protect the internal startup from the parent organization? I would like to reframe and reverse the question: How can we protect the parent organization from the startup? In my experience, people defend themselves when they feel threatened, and no innovation can flourish if defensiveness is given free rein
17. We can see and feel the waste of material things. Awkward, inefficient, or ill-directed movements of men, however, leave nothing visible or tangible behind them. Their appreciation calls for an act of memory, an effort of the imagination. And for this reason, even though our daily loss from this source is greater than from our waste of material things, the one has stirred us deeply, while the other has moved us but little
