Sales reps who close business have no business cold calling.
Sales development is a fundamental piece of developing a successful B2B sales and marketing qualification strategy. Outbound tele-prospecting / tele-qualification, cold calling, relationship building, etc are each well-documented versions of sales development, yet they are also often mishandled. Many companies will have closing sales reps (Enterprise Reps, Outside Reps, AEs, etc) be responsible for their own sales development results. The result is a negative impact on pipeline and closed revenues.
