Design management is a way to help people make things look good and work well. It's like when you want to make a birthday card for your friend, design management will help you decide what kind of pictures, colors, and words to use, so it will look nice when you give it to your friend.
Design management also helps companies make good products. Just like your card, companies need to think about what colors, pictures, and words to use when they make things like toys or cars. They also have to think about how the product will work and how people will use it. This way, the product will look good and work well for the people who use it.
Design management helps people work together to make sure everything looks and works the way it should. So, just like how you and your friends can work together to make a great card, people in design management work together to make great products.
