SBC Ameritech needed a technical sales manual for both internal and external sales people, explaining how to sell its OmniPresence telecommunications service for Internet Service Providers (ISPs). Services geared for ISPs are based on existing technologies, but selling them requires different sales propositions and an understanding of how ISPs provide services to their customers. The manual had to make clear the distinction between OmniPresence and other services, as well as services provided by competing companies. Working from diverse source materials—both engineering and marketing documents—we created a two-section manual. Section 1 describes what OmniPresence is and how it fits the service model used by dial-up ISPs. Section 2 presents strategies for selling OmniPresence and instructions for setting up new customers.
