How often should a company perform an analysis of their marketing activities?

The frequency of marketing analysis may vary depending on the size of the company, the complexity of the marketing strategy, and the industry in which the company operates. However, most companies perform marketing analysis on a quarterly or annual basis to evaluate the effectiveness of their marketing strategies and make data-driven decisions for future marketing efforts. Additionally, companies may conduct ad hoc analysis when launching a new product or campaign to ensure that their marketing efforts are on track to achieve business objectives.
