Look for a very compelling strategy such as low cost leadership, differentiation, market segment/niche, innovation, etc. that you learned this week, and describe the strategy and why it is successful to that particular business. It could be one of your favorite companies or one you admire.
Please avoid big names like Amazon, Walmart, Apple, Starbucks, etc, and concentrate more on your favorite shop in your neighborhood, a small business you really like, your family business or your favorite restaurant, etc.
