Product Marketing, Product Marketing

Product marketing, as opposed to product management, deals with more outbound marketing tasks. For example, product management deals with the nuts and bolts of product development within a firm, whereas product marketing deals with marketing the product to prospect, customers, and others. Product marketing, as a job function within a firm, also differs from other marketing jobs such as Marcom or marketing communications, online marketing, advertising, marketing strategy, etc.

However, as the company grows someone needs to focus on creating good requirements documents for the engineering team, whereas someone else needs to focus on how to analyze the market, influence the "analysts", press, etc. When such clear demarcation becomes visible, the former falls under the domain of product management, and the latter, under product marketing. In Silicon Valley, in particular, product marketing professionals have considerable domain experience in a particular market or technology or both. Some Silicon Valley firms have titles such as Product Marketing Engineer, who tend to be promoted to managers in due course.
