Meet GRASP. It Is Still Not Too Late

I kept reading on Craig's Apply UML and Patterns and came to Chapter 17 - GRASP: Designing Objects with Responsibilities. This is a very important chapter. I'm lucky that I was caught by it in the right time, just before I was otherwise going too far. I thought I should start working on System Architecture design. I now know I have to carefully assign responsibilities to objects in the first place before I move on. It's worth to pause the development progress for a little while, hopefully for a better result.
