I'll be honest, about half way through this book, I thought that I found it rather bland and full of things that I was already doing. This changed however as I was assessing an application that I had been working with for years and we had found some critical faults in.
I started thinking more about the book and the contents of it. After re-reading it, I realized that I hadn't been looking closely enough for faults, only going just beneath the skin. As I started to apply more and more of the information within, I began to realize more and more of what I had been learning was adding tremendously to the quality of the product.
In short, after thinking more and more about this book, it's quickly gone to one that I recommend to everyone that I work with.
