"Marketing managers develop the firm's marketing strategy in detail. With the help of subordinates, including product development managers and market research managers, they estimate the demand for products and services offered by the firm and its competitors. In addition, they identify potential markets - for example, companies, wholesalers, retailers, government, or the general public. Marketing managers develop pricing strategy to help firms maximize profits and market share while ensuring that the firm's customers are satisfied. In collaboration with sales, product development, and other managers, they monitor trends that indicate the need for new products and services, and they oversee product development. Marketing managers work with advertising and promotion managers to promote the firm's products and services and to attract potential users."
