Those 3 for the most part don't have to work together. They need to run on the same CPU without taking more than their allowed portion of the CPU.

If they have to work together the communication protocol is clearly defined well in advanced and limited to exactly what they need to say. Thus we are reasonably sure if any one combination works all possible combinations will work. Even then there is typically higher level control to only release combinations that are tested to work together.

That sounds good in theory. The reality I live in, is different though. If it works for you, that’s great!
