Software factories have been around for some time now originating from work done at the SEI. http://www.sei.cmu.edu/plp/plp_init.html

Recently Keith Short and Jack Greenfield from the VS Enterprise Tools group have been writing a book on the subject. Jack has a good introduction in terms of photography at http://msdn.microsoft.com/architecture/community/newsletter/default.aspx#Contemplate3 and the web site for the book is at http://www.softwarefactories.com/.

Finally the book will be available in July from amazon at http://www.amazon.com/exec/obidos/tg/detail/-/0471202843/qid=1081956906/sr=1-1/ref=sr_1_1/102-9718537-7522515?v=glance&s=books. Have a look at the book description on this site.
