As a student studying business strategy, I've found Michael Porter Competitive Advantage Model to be insightful. His model explains how companies can gain an edge over competitors using three key strategies: cost leadership, differentiation, and focus. The Five Forces Theory, which Porter also developed, helps analyze industry dynamics like competition, new entrants, and supplier power. Understanding these forces is crucial because they shape how businesses should position themselves to thrive. It’s a powerful tool, especially when working on assignments or projects about business strategies, and definitely something I’ll keep in mind for future exams.
