Comprehensively analyzing software architectures can be simplified by working along significant attributes. ATAM (Architecture Trade off and Analysis Method) from SEI was developed by Carnegie Mellon University. Between 2006-2009 I visited Carnegie Mellon and took several courses and got myself certified as a Software Architect. The primary benefit was to gain an appreciation of trade-off analysis based on specific attributes across facets of architecture.
It is another tool in the strategic and objective thinking toolbox that every enterprise architect needs. For more information: http://www.sei.cmu.edu/architecture/tools/evaluate/atam.cfm
