Buy the book: Software Developer's Guide by Whil Hentzen
This book cover all except the programming...

from the site:

There are plenty of books that show you how to write applications in a specific language. They do a marvelous job of explaining the nuts and bolts of the syntax and the use of the tools to build applications with the latest features and functionality available. There are also a number of fine books that show you how to be "a computer consultant." But there are a whole host of issues specific to the business of writing, delivering and supporting custom software systems. The Software Developer’s Guide, Third Edition, is the only book that will take you on a step-by-step tour of the entire process. “DevGuide 3”, with over 150 pages of new material, shows you how to do "The Other 90%" of the work involved in producing custom software applications.
