LEAN STARTUP Part 1 5 

What is a Lean Startup? 6 A Startup is a search for a repeatable and scalable business model. The Customer Development process is the way startups quickly iterate and test each element of their business model. Agile Development is the way startups quickly iterate their product as they learn. A Lean Startup is Eric Ries’s description of the intersection of Customer Development, Agile Development and if available, open platforms and open source. – Steve Blank, author of The Startup Owner's Manual 

Iridium woes (Fail fast) •  Conceived in 1987 by Motorala •  Bought a fleet of 15 rockets from Russia, the U.S. and China •  Built and launch 72 satellites •  Nine months after the first call was made in 1998, Iridium was in Chapter 11 bankruptcy. 7 5.2 billion dollar business plan mistake No Business Plan Survives First Contact With A Customer – Steve Blank, author of The Startup Owner's Handbook 

Feedback Loop 8 Ideas   BUILD   Code   MEASURE   Data   LEARN   BUILD – MEASURE – LEARN The fundamental activity of a startup is to turn ideas into products, measure how customers respond, and then learn whether to pivot or persevere. All successful startup processes should be geared to accelerate that feedback loop. – Eric Ries, author of The Lean Startup
