Marketing managers must analyze their organization's environment to develop effective strategies. This involves analyzing both the micro and macro environment. The micro environment comprises suppliers, intermediaries, customers, competitors, and public. The macro environment includes political/legal, economic, social/cultural, technological, demographic, and natural forces. Managers use frameworks like PEST to systematically analyze these external factors. Regular environmental scanning and incorporating findings into planning is crucial due to increasing complexity and pace of change. However, many organizations have poorly developed scanning systems.
