The book was quite repetitive, and my role straddles design and development, so it was a bit simplistic for setting a foundation. Perhaps for someone in web design purely in design (very little actual coding), and completely new the the concept of design systems, this book would be useful. I did find some use, but I've already started on a system and put a bit of thought into it. At this point I need more practical and substantive guidance, for writing documentation and developing workflows. That isn't in this book.
