The purpose of these lessons is to encourage students to apply knowledge of the marketing mix to a variety of real life products and services. The intention is that students should take what they know and use that information in developing an understanding of the blending of the elements of the marketing mix. It also aims to develop the ability to make judgments, given that the student will have to think about the relative importance of the elements of the mix and the way in which different products and services are marketed. The inclusion of services in the list of potential sources of investigation is designed to get students thinking about the impact of the 'additional' three P's - people, process and physical environment.
