This case study examines the marketing strategies of Marks and Spencer (M&S) and Zara, focusing on their use of the marketing mix (7 Ps). The study begins with an introduction to marketing and its importance, particularly in the context of retail. Task 1 delves into the role of marketing within an organization, specifically how the marketing department interrelates with other functional units such as human resources, finance, research and development, sales, operations, customer service, and information technology, using M&S as an example. Task 2 compares the marketing mix elements (7 Ps: Product, Price, Place, Promotion, People, Process, Physical Evidence) employed by both M&S and Zara. The analysis highlights the differences in their approaches to pricing, distribution, and promotion. Task 3 then focuses on developing a marketing plan for Marks and Spencer, outlining key strategies for market analysis, segmentation, targeting, positioning, and the formulation of marketing objectives. The conclusion summarizes the key findings, emphasizing the importance of adapting marketing strategies to meet consumer needs and achieve organizational goals.
