The Great Retail Debate explores the challenges retailers face when expanding into international markets, focusing on the balance between global consistency and local adaptation. David and Martin discuss examples including Tesco, Walmart, McDonald’s, IKEA, Zara, Aldi, Lidl, and Gymshark to show how brands can protect their core proposition while adapting to local customers, economics, and competition. The episode highlights the importance of understanding what makes a business successful, learning from local markets, and knowing what to change and what not to change before scaling internationally.
