A process model is a way of looking at how something works. It breaks down a complicated task or problem into smaller steps, so it's easier to understand. It helps us understand how different parts of a system work together and how we can change parts of the system to make it work better. Think of a process model like a map that shows the different paths that you can take to get from one place to another. The same goes for a process model--it shows the different steps that you need to take to get from one place to another.
