Imagine you want to sell lemonade, and you know a new recipe for making it. But before you can start selling the new recipe, you tell everyone that you're going to sell it soon. People hear about the new recipe and decide to stop buying your current lemonade, even though the new recipe isn't ready yet. So, you end up losing money because people stopped buying your current lemonade, which is the Osborne Effect.
The Osborne Effect is when a company announces a new product that they plan to release in the future, and people stop buying the current product because they want to wait for the new one. This can hurt the company because they're losing money when people stop buying the current product, and they might not be ready to start selling the new one yet. It's like telling everyone about your new lemonade recipe before you're ready to start selling it.
