English to Portuguese Marketing Advertising / Public Relations

The work of copywriters and other creative advertising practitioners is directed by a framework known as a creative brief, which is a document designed to channel copywriters’ and other creatives’ efforts toward a solution that will serve the interests of the client. The term brief is used to mean that a client for an advertising project (such as a brand management team) is informing, or briefing, an advertising agency of the client’s needs and expectations for a proposed advertising campaign. The creative brief represents an informal pact between client and advertising agency that represents agreement on what an advertising campaign is intended to accomplish.
