DSRP, Distinction, System Thinking
Distinction is a part of four simple rules in DSRP. Distinctions can be made between and among things or ideas, and the distinction rule is any idea or thing that can be distinguished from the other ideas or things it is with. These are a list of closely related concepts that stem from distinctions.
The best resource to get a better understanding of DSRP is the book:
