A useful way to understand ROS & ROS2 is to separate the goal, the input, the model or tool, and the way the output is evaluated.

One important area is data quality. Define what a good result looks like before changing tools or settings, then test one variable at a time so you can tell what actually improved the outcome.

Another area is security. Keep examples of both strong and weak outputs, check important facts or generated code independently, and document settings that produce consistent results.

The main takeaway is that ROS & ROS2 becomes much more reliable when the workflow includes clear inputs, repeatable checks, and a way to learn from previous results.

I think ros and ros2 is the key part of this topic. A practical approach is to define the outcome you want, test it with a small example, and then check quality, speed and reliability separately. That way you can improve the workflow without losing track of what caused the improvement.
