Pinnacle of PRPC development
As Software engineers , the pinnacle of PRPC development is creating your own custom rules which goes through the Rules assembly or First Use Assembly ( FUA ) process. You might wonder why someone should put custom rules creation at the top, frankly the reason is when you design a custom rule and finally implement it, you are exposed to the wonderful design of Pega itself and you slowly understand the inner workings of PRPC. The moral of the story: Don’t be stuck in a higher level abstraction layer, go down and explore how the creature is build, then only you will understand its behavior.
