It looks like nobody needs the explanation of the Lean Startup method in 2018 anymore. But here it is to be sure that everybody in tourism business understands it too. According to the entrepreneur, blogger, and author of The Lean Startup, Eric Ries:
"The Lean Startup provides a scientific approach to creating and managing startups and get a desired product to customers' hands faster. The Lean Startup method teaches you how to drive a startup-how to steer, when to turn, and when to persevere-and grow a business with maximum acceleration. It is a principled approach to new product development.
Too many startups begin with an idea for a product that they think people want. They then spend months, sometimes years, perfecting that product without ever showing the product, even in a very rudimentary form, to the prospective customer. When they fail to reach broad uptake from customers, it is often because they never spoke to prospective customers and determined whether or not the product was interesting. When customers ultimately communicate, through their indifference, that they don't care about the idea, the startup fails." - http://theleanstartup.com/principles
And why the lean start-up changes so many things?
"While some adherents claim that the lean process can make individual start-ups more successful, I believe that claim is too grandiose. Success is predicated on too many factors for one methodology to guarantee that any single start-up will be a winner. But on the basis of what I’ve seen at hundreds of start-ups, at programs that teach lean principles, and at established companies that practice them, I can make a more important claim: Using lean methods across a portfolio of start-ups will result in fewer failures than using traditional methods.
A lower start-up failure rate could have profound economic consequences. Today the forces of disruption, globalization, and regulation are buffeting the economies of every country. Established industries are rapidly shedding jobs, many of which will never return. Employment growth in the 21st century will have to come from new ventures, so we all have a vested interest in fostering an environment that helps them succeed, grow, and hire more workers. The creation of an innovation economy that’s driven by the rapid expansion of start-ups has never been more imperative." - https://hbr.org/2013/05/why-the-lean-start-up-changes-everything
