I've been working professionally as a software engineer for several years and I learned more in the first 100 pages of this book than from my years of experience in the industry. Scott Berkun provides examples from real world experiences so you don't have to make the same mistakes to learn what you should and shouldn't do.
The topic of project management is a potentially dull subject but the conversational tone, with the occasional humor makes the read pleasant and engaging.
Even if you're not a manager, the information provided in the book is essential to make you aware of the issues that projects face and what you can do to avoid the common pitfalls of software development.
I highly recommend it for all members of a team that has to design, implement, test and deliver (on time, no less) a product in some form or another.
To give you a deeper overview, here's a short biography from the back of the book cover.
Scott Berkun worked for 10 years at Microsoft Corporation on projects including Internet Explorer, MSN and Microsoft Windows. He worked for two years in Microsoft's engineering excellence group, teaching and consulting with development teams. He currently works as an independent consultant in project management and product design and he runs the pmclinic, a friendly discussion forum on project management issues at www.scottberkun.com.
Incidentally, I was first introduced to Scott's work by subscribing to the pmclinic mailing list. If you're involved with project management issues, the forum is a great way to learn how others are solving the problems and challenges you face on a regular basis.
