They focus on understanding accounts at a high level by considering size of opportunity and likelihood. Analytics models assign scores to prioritize accounts. Automation uses triggers from user behavior and signals to proactively engage customers. Key learnings include the need for cross-functional partnerships and an experiment-measure approach to continuously improve the system. The goal is to leverage LinkedIn's data to power the most effective sales and marketing.
