Recently I got a book that called “Lean Start Up” by Eric Ries. Wonderful book must read to those who thinking of being entrepreneur filled with amazing example of good and bad business practises. Mainly it propagandises the core idea of Lean Start Up and the whole books circulates around that notion. The Lean Start Up concept is that: when you want to launch a product, you must create MVP(Minimal Viable Product) that product might lack a lot features to be final product, but it is just your tool for learning for your final release. Book emphasises the importance of learning and gathering data when you launch MVP and that learnt knowledge will help you to analyse and craft the ultimate product. However, you will have to go through several iterations of MVP until you reach that product. BUILD->MEASURE->LEARN are the core mantras that you have to go over and over.
