You  generally find some of Big slow moving companies (old time pioneers )and lots of medium companies offering only cost advantage and few small comapnies which are fast and niblle who bring new disruptive product and services in market . While big companies tend gain fat and decision taking is buried in huge layers of redundant management a typical decision will take months and strategic decisions will take years .While big company have advantage of inertia , branding image (or reality distortion field )they tend to turn blind to user requirements after some time , due high degree of compartmentalization of people and horizontal work profile (for example tech and marketing folks don’t mix ).Big hierarchy also means trickle down effect and ambiguous responsibilities . Big Companies are more reactive , like intel they need good competition to keep them innovative .

Small companies with disruptive products and services with flatter hierarchy can make fast inroads to markets only thing they need to do is sustain innovation and market
