Here at [P1], we practice Agile. In Agile development, the goal is to move fast, adapt to changes, and make improvements easily. If you isolate different parts of the system – like separating the code for handling user login from the code for game mechanics – you make life easier for everyone.

1. Easier to understand: When things are isolated, it's simpler to grasp what each part does. You don't need to understand the entire system to work on one isolated module.

2. Fewer mistakes: You're less likely to mess up other parts of the system if you're only working on one isolated piece. It's like playing with building blocks. If you mess up one, the whole tower doesn't fall.

3. Easy to test: You can test one piece at a time without worrying about the rest. If something breaks, you know exactly where to look.

4. More flexibility: If you want to change how something works or add a new feature, you can do it without having to rewrite or adjust other unrelated parts.

5. Better collaboration: In a community like ours, where lots of people are working together, isolated parts mean multiple people can work on different things at the same time without stepping on each other's toes.

6. Easy to replace: If a particular piece of your system becomes outdated or there's a better way to do it, it's easier to swap it out if it's isolated.

So, isolating different parts of your system helps you move fast, reduces errors, and makes collaboration smoother, which are all key goals in Agile development.
