I heard about this book when I started working in the software industry, a while after the anniversary edition came out. Now it's over 40 years since the original publication.

I cannot emphasise this enough: every single thing the industry struggles with today is laid out in this book, root causes are identified, and strategies for coping with the issues are laid out. Every single thing. And still, the industry struggles.

This should be mandatory study for everyone seeking to enter the field.
