Imagine you have a favorite toy that you like playing with. If you want to make more toys that look and work exactly like your favorite toy, you might use a machine to make them. This machine is called a factory.
Software factories are like the machines that make toys, but instead of making physical objects, they create computer programs. These programs are made using a set of rules and procedures that are repeated over and over again to create software that works the same way every time.
Just like a toy factory needs people to set up the machines, software factories also need people to write the code and set up the rules for creating software. These people are called software engineers.
So, software factories are places where software engineers use predefined rules, tools, and techniques to create software programs quickly and efficiently. It's like a big workshop with lots of people working together to make new programs. And, just like toy factories, the goal of a software factory is to create lots of high-quality programs that work well and are easy to use.
