The
ubiquity of mobile devices provides new opportunities to warn people of
emergencies and imminent threats using location-aware technologies. The
Wireless Emergency Alerts (WEA) system, formerly known as the Commercial Mobile Alert Service (CMAS), is the newest addition to the Federal Emergency Management Agency (FEMA) Integrated Public Alert and Warning System (IPAWS),
which allows authorities to broadcast emergency alerts to cell phone
customers with WEA-enabled devices in an area affected by a disaster or a
major emergency. This blog posting describes how the Software Engineering Institute's (SEI) work on
architecture, integration, network security, and project management is
assisting in implementing the WEA system, so it can handle a large
number of alert originators and provide an effective nationwide wireless
emergency warning system.

A key mission of the SEI is to advance the practice of software engineering and cyber security through research and technology transition
to ensure the development and operation of software-reliant Department
of Defense (DoD) systems with predictable and improved quality,
schedule, and cost. To achieve this mission, the SEI conducts research
and development (R&D) activities involving the DoD, federal
agencies, industry, and academia. One of my initial blog postings
summarized the new and upcoming R&D activities
we had planned for 2011. Now that the year is nearly over, this blog
posting presents some of the many R&D accomplishments we completed
in 2011.

Senior Member of the Technical Staff,

Bursatec,
the technology arm of Groupo Bolsa Mexicana de Valores (BMV, the
Mexican Stock Exchange), recently embarked on a project to replace three
existing trading engines with one system developed in house. Given the
competitiveness of global financial markets and recent interest in Latin
American economies, Bursatec needed a reliable and fast new system that
could work ceaselessly throughout the day and handle sharp fluctuations
in trading volume. To meet these demands, the SEI suggested combining
elements of its Architecture Centric Engineering (ACE) method, which requires effective use of software architecture to guide system development, with its Team Software Process (TSP),
which teaches software developers the skills they need to make and
track plans and produce high-quality products. This posting—the first in
a two-part series—describes the challenges Bursatec faced and outlines
how working with the SEI and combining ACE with TSP helped them address
those challenges.
