This course does not teach fashion. It structurally interprets how retail works. Sales are not merely the result of selling; they are the outcome of a system where KPI design, goal management, inventory turnover, workforce operations, and the strategic gap between headquarters and the field are all interconnected. Stagnant sales and organizational conflicts are not issues of emotion, but issues of design. Through the interpretation of sales structures, the principles of KPI operation, the design of operational frameworks, and the analysis of strategic conflicts, this course redefines retail from the perspective of data and structure. It is a process of moving beyond simply understanding retail to gaining the vision to design it.
