Large-Scale Software Architecture : A Practical Guide using UML 

Rating:
Summary: Excellent ref. on communicating large-scale software design
Review: An excellent reference on what UML diagrams to use to capture the achitecture of a large software project. And this isn't based on the authors' ivory-tower opinions, but on their actual experience of using these diagrams in the real world. We have since used their approach to successfully capture (and thereby communicate to others) the architecture of software projects at our company.

The writing style is a bit dry (there are no humorous anecdotes), but this is more than made up for by being concise.

The book also includes an excellent primer of the various roles a software architect (and other software managers) should take within a large project.
