You can’t ask that question without also asking, “How is the Marketing Automation and CRM working for you?” Both valid questions. Both entwined with each other. Both dependent on each other in a performance oriented dance that is more easily measured than most people let on.
Of course, everyone declares that lead generation can be measured and tracked and refined and repeated, but does it happen in the common everyday B2B company? It is happening in the largest B2B companies and it may be happening more than some admit, because who wants to admit it openly and let their competitors know that they have figured out the secret sauce for growth?
