This is true startup productivity: systematically figuring out the right things to build. - Eric Ries

Una startup es una institución humana diseñada para crear un nuevo producto o servicio bajo condiciones de incertidumbre extrema.

Remember, planning is a tool that only works in the presence of a long and stable operating history. And yet, do any of us feel that the world around us is getting more and more stable every day? Changing such a mind-set is hard but critical to startup success.
