" Product managers are the connection between customers and the engineers who build the product. You are a bridge between what customers say and what the organization actually builds. You sit at the epicenter of everyone in your organization who builds, markets, sells, and supports your product. You explain what engineering is building to the people in sales and support. You interact with legal. You interact with finance. You are the ambassador for your products inside and outside the company. You are everything. "
