Although this book has been reprinted recently, all the data dates back to the late-1990's. Social and economic data are perhaps presented for illustrative purposes only, however, it is a bit disheartening.

There are some interesting project data, financial models and checklists, but frankly, the reader could figure those out on his/her own with some common sense and marginal experience in the industry.

Bottom line -- my suggestion is to review the book at the public library before you buy.
