How to Not F*** Up Your First 90 Days as a CMO
Sam Mallikarjunan

Perhaps this is the result of the age’s old sales strategy that says every new lead is a good lead. And then both sales and marketing invest equal amounts of resources pursuing them. There should be a systematic way of sorting leads out when they come in.
 One disadvantage to inbound leads is that they give both sales and marketing the sense that this is a particularly good lead because they sought you out. Therein is a paradox: the customer is thinking you might have something they want to buy and then your teams start to try to fill the need whether you truly can or not. There may be a mismatch in company operations, organizational profile and in purchasing especially if there is going to be a complex sales cycle.
