Summary: The Lean Startup Eric Ries

Those teams should be putting a number of minimally viable products into the marketplace and figuring out how to make them work. Even established companies should be using the Lean Startup methodology on an ongoing basis

Lean Startup method is not opposed to building high-quality products, but only in the service of winning over customers. We must be willing to set aside our traditional professional standards to start the process of validated learning as soon as possible.

real life, being an entrepreneur is more of an exercise in management skills than anything else. Any startup is a portfolio of activities, all happening simultaneously. At any time:
New customers are being acquired.
Existing customers are being supported.

If you have a complex product and it’s hard for people to visualize what the finished thing will look like, you might consider making a video which you can then share. The video can describe what your end product will do.

Create and run true split-test experiments which compare how customers respond to the innovation as opposed to how they respond to the current offering.

Most startups have found the best approach is to focus on just one growth engine at a time. There’s frequently just one growth engine which will be a good fit for an enterprise and for a product. And just to make this selection process even more interesting, all engines of growth eventually and naturally run out of gas. They run their course and then growth slows or stops.

Without this, it won’t be possible for your people to do high quality work as they will be constantly obsessing over getting new stuff out the door. You have to achieve both scale and quality to succeed

The smaller your batch size is, the faster you can get through the Build-Measure-Learn feedback loop. If you can get through that loop faster than your competitors can, then it stands to reason you will learn more than them.

Test all your leap-of-faith assumptions rigorously. Then decide whether you need to pivot or persevere to succeed

Why do so many startups fail? The business myth says: A lone entrepreneur – beavering away in a lab or a garage somewhere – through hard work, grit and sheer perseverance develops a great product which then becomes a blockbuster hit. That sounds appealing but the reality is most startups tend to burn through their resources and then disappear because they never get around to seeing what their potential customers think of what they’re developing. They worry about the product first and assume customer demand will be there automatically.
