I try to avoid reviewing esoteric information technology publications here. I am not an engineer, so I think reviews of such works would be better left to those who are.
There are occasional exceptions, however, and one of them is Finding Services for an Open Architecture. Originally written to help the U.S. Navy in its exploration of a service-oriented open architecture, the work provides non-military IT experts, administrators, and executives with a fascinating and incredibly thorough case study.
If you run or manage IT systems, this short work is worth a read.
