a system fails, engineers too often focus on the physical components,
but pay scant attention to the software. In software-reliant systems
ignoring or deemphasizing the importance of software failures can be a
recipe for disaster. This blog post is the first in a series on recent
developments with the Architecture Analysis Design Language (AADL) standard.
Future posts will explore recent tools and projects associated with
AADL, which provides formal modeling concepts for the description and
analysis of application systems architecture in terms of distinct
components and their interactions. As this series will demonstrate, the
use of AADL helps alleviate mismatched assumptions between the hardware,
software, and their interactions that can lead to system failures.

Happy Memorial Day. As part of an ongoing effort
to keep you informed about our latest work, I'd like to let you know
about some recently published SEI technical reports and notes. These
reports highlight the latest work of SEI technologists in architecture analysis, patterns for insider threat monitoring, source code analysis and insider threat security reference architecture.
This post includes a listing of each report, author(s), and links where
the published reports can be accessed on the SEI website.

plays a critical role in the development of software-reliant systems.
Even with the most diligent efforts of requirements engineers,
designers, and programmers, faults inevitably occur. These faults are
most commonly discovered and removed by testing the system and comparing
what it does to what it is supposed to do. This blog posting summarizes
a method that improves testing outcomes (including efficacy and cost)
in a software-reliant system by using an architectural design approach,
which describes a coherent set of architectural decisions taken by
architects to help meet the behavioral and quality attribute
requirements of systems being developed.
