Agile software development is like building a toy with your friends.
First, you decide what toy you want to make and talk about how you want it to work.
Then, you break the toy into smaller parts, like the body and the arms and the legs.
You and your friends take turns building each part, and then you put them all together to see how it works.
If it doesn’t work perfectly, you talk about how to make it better and then try again.
This way, you can make the toy faster and make sure it works the way you want it to.
