This book is one of the classics on the subject. Coad and Yourdon have been among the pioneers on OO methodologies, and their one is a well respected account.
What they provide is a complete methodology that covers all the software engineering phases, from analysis (with this book) to implementation (their OOP book).
You'll find that specialized magazines routinely presents articles that compares various methodologies. In each of them you'll always find Coad-Yourdon one. For this reason, despite the book is a bit old-dated, it worths a read and, indeed, it can be easily red. You'll gain a better understanding of the modern OO literature, and some insights that are timeless.
