This document provides an overview of a playbook to help B2B marketers transition to a more customer-obsessed organization. It recommends that B2B marketers shift from a focus on products to understanding customer outcomes, build systems for customer insight and engagement across channels, and manage marketing performance across the entire customer lifecycle. The playbook guides marketers through discovering their current state, planning the transition, operationalizing changes with a focus on customer engagement, and optimizing programs. The goal is for B2B marketing to measure business outcomes rather than just outputs and to make marketing more helpful, handy and human-centered.
