A product manager is like a big boss for a product, just like a chef is the big boss of a kitchen. They're in charge of making sure the product meets the needs of the people who will be using it and that it is successful. They often work with teams of other people like engineers, designers, and marketers to make this happen. They also help decide what features the product should have, what kinds of problems it can solve, and how the user will interact with it. They also help figure out how the product should be priced and marketed.
