An information required for marketing planning is the previous year's sales volume.
Marketing planning is the process of creating a roadmap for achieving a company's marketing objectives. It involves identifying the target audience, determining the product or service to offer, setting prices, deciding on distribution channels, and developing promotional campaigns.
One crucial piece of information required for marketing planning is the previous year's sales volume. This information provides insights into the current market share of the company, the growth or decline trends in sales, and the factors that contributed to the sales performance.
By analyzing the sales volume, a company can determine the effectiveness of its previous marketing strategies, identify areas that require improvement, and make informed decisions about future marketing plans. For instance, if the sales volume has been declining, the company may need to revise its product offering, adjust the prices, or adopt new marketing channels or tactics to reach a wider audience.
Therefore, the correct answer to the question is that an information required for marketing planning is the previous year's sales volume, as it provides valuable insights into a company's past performance and helps in making informed decisions about future marketing strategies.
