A marketing research plan always needs to be part of a companys overall business plan. For example, without a good marketing research process it will be difficult to know how customers feel about the service and products of the company. A companys marketing research plan will help it gather information about its markets and help it complete a market segmentation and focus on target marketing.
Marketing research can also help a company with decision making, such as whether or not to grow its business, or add new products or services. Research is also useful when a company is planning on how to provide good customer service, and when recruiting employees and hiring additional sales people.
