“If you want to move at the speed of “now, light, big data, thought, stuff,” pick your big data analytics battles. If your business is currently too chaotic to support a complex model, don’t build one. Focus on providing solid, simple analysis until an opportunity arises that is revenue-important enough and stable enough to merit the type of investment a full-fledged data science modeling effort requires.” John Foreman ( 1/30/2015 )
