I once drove demand generation globally for four product programs. Each program had a marketing director who led a small team of marketers. They were responsible for product use cases: disaster recovery, applications, databases, and business intelligence. The marketing directors developed unique value propositions, messages, proof points, customer success stories, and target lists of buyers and influencers for their programs. They also provided direct support of sales activities, and served as industry pundits. And, they came to me to generate demand so their programs' value could be measured in leads, opportunities, and sales revenue.
It was chaos.
