Final answer:
The advertising manager in a centralized system is responsible for planning, budgeting, and overseeing the development and execution of advertising campaigns, contrary to the suggestion that they do not engage in such activities. Their role includes a broader range of responsibilities than that of an art director in a decentralized organization.
Step-by-step explanation:
The role of an advertising manager in a centralized system encompasses various aspects of strategizing and executing advertising campaigns within an organization. Contrary to the statement that an advertising manager does not deal with planning and budgeting, their responsibilities actually involve significant planning and budgeting tasks. An advertising manager must develop comprehensive advertising strategies, allocate budgets efficiently to various media channels, oversee the creative development of adverts, and monitor campaign performance to ensure that the advertising objectives align with the company's goals.
Therefore, the statement that the advertising manager does not deal with planning and budgeting is false. Additionally, while there may be some overlap in the creative aspects of their roles, the functions of an advertising manager are not entirely similar to those of an art director in a decentralized organization, as the advertising manager typically has a broader scope of responsibilities that encompass strategic and business decision-making beyond the creative realm.
