It is a very interesting book. Anyone having been involved in a large scale software development projects will recognize typical problems often seen in this type of projects while reading this book and by experience we have developed an intuition about how to deal with the complexity inherent to large scale projects. Mr Lakos book is the first, to my knowledge, that address this subject and it formalize extremely well the problems of large scale projects and propose a methodology and principles to apply to keep the development and maintainability of these projects manageable. It is a very refreshing C++ book and I recommend it to any C++ professionals not having read it yet.

The most interesting chapters in my opinion are chapter 5 and chapter 6. Chapter 5 presents refactoring methods to remove cyclical dependencies among components, reduce inter dependencies and how to layout components into software layers that will ease reusability and maintainability. Chapter 6 discuss about component insulation. Its difference with encapsulation, the benefits of component insulation and its cost and when it is wise to avoid insulation.
