First of all, I like your signature -- "Complexity is Easy, Simplicity is Hard !"
This has been my overarching goal in this book.
I gathered all the design principles out there, make sense out of them, organize/filter/relate them, write concise definitions and explanations, and package them in a short book.
What's unique about this book is the synthesis of all the design principles. Many of the principles are complementary and contradictory in nature, I've carefully identified all these and put them on a single diagram to help you choose the correct principles for your need.
And another goal of the book is to make it "an easy read" -- using plain English language, lots of visuals, and can be read over a weekend.
You'll be the judge if I accomplished my goals
