These may include conducting focus groups about advertisements or products, gathering information about customers, or designing advertisements. This individual also helps develop new strategies and plans of action for marketing new products or overhauling old marketing plans.An assistant marketing manager usually needs a bachelor’s degree in marketing or a related field. In addition, expert organizational skills and communication skills are a must, as the individual must be able to converse effectively with both subordinates and supervisors to develop and carry out new strategies. Finally, previous experience in marketing may be required by potential employers.
