Marketing involves a range of processes concerned with finding out what consumers want, and then providing it for them. This involves four key elements, which are referred to as the 4Ps. A useful starting point therefore is to carry out market research to find out about customer requirements in relation to the 4Ps.
There are two main types of market research - quantitative research involving collecting a lot of information by using techniques such as questionnaires and other forms of survey. Qualitative research involves working with smaller samples of consumers, often asking them to discuss products and services while researchers take notes about what they have to say. The marketing department will usually combine both forms of research.
