What are the importance of research in the marketing of any product?

While research is key to marketing decision making, it does not always need to be elaborate to be effective. Sometimes small efforts, such as doing a quick search on the Internet, will provide the needed information. However, for most marketers there are times when more elaborate research work is needed and understanding the right way to conduct research, whether performing the work themselves or hiring someone else to handle it, can increase the effectiveness of these projects.
