Business management is like becoming the leader of a pretend game where you and your friends are pretending to run a store. Just like how you make the rules in your pretend game, a business manager makes rules and plans for how a real business should run.
They make sure everyone is doing their job, the store is making money and customers are happy. They also make decisions about what products to sell and how much to charge customers for them. It’s kind of like being the boss of the game, but for a real business!
