FALLS CHURCH, Va., Nov. 29, 2004  /PRNewswire/ -- Raytheon Company's
Intelligence and Information Systems (IIS) operation here recently attained
the Software Engineering Institute's (SEI) Capability Maturity Model
Integration (CMMI) Maturity Level 3 rating for systems and software
engineering.

    Carlos Galvan, a SEI-authorized CMMI lead appraiser at the Center for
Systems Management, led an independent, third-party appraisal team that
conducted the review.

    This latest achievement follows a long history of process improvement in
Intelligence and Information Systems starting with the adoption of SEI's
Software Capability Maturity Model in the early 1990s and later adoption of
equivalent models for systems engineering.

    "This rating tells our customers and partners that our Falls Church
operation successfully manages its processes, and that we're committed to
delivering better solutions to our customers," said Mike Keebaugh, IIS
president. "It also shows the quality and maturity of our processes, and that
we can provide solutions more efficiently and effectively."

    CMMI is the newest standard for benchmarking the commercial and defense
industry's best practices for product development. Raytheon has been a major
contributor to the development of the CMMI model. CMMI levels are increasingly
used by government agencies and contractors to evaluate the potential for
organizations to produce quality products on time and within budget. The
Maturity Level 3 rating indicates that the defined and documented processes
for developing and maintaining products at Raytheon's Falls Church operation
have been integrated into previously existing process documentation and is
institutionalized at the site.

    Raytheon IIS employs more than 750 engineers at its Falls Church site, and
the company provides superior solutions for defense and government customers,
specializing in signal and image processing, geospatial intelligence, air- and
space-borne command and control, ground engineering support, weather and
environmental management, homeland security and information technology. IIS
had 2003 sales of $2 billion, and employs 8,600 professionals at major sites
here, in Aurora, Colo., and Garland, Texas, its headquarters.

    Raytheon has a three-pronged approach to achieving process excellence:
Integrated Product Development System, an integrated set of best practices
tailored for the entire product life-cycle; Raytheon Six Sigma(TM), tools that
deliver value and integrate best practices for continuous process improvement;
and CMMI, process requirements and appraisal methods for creating, measuring,
managing and improving specific processes to assess process maturity.

    The SEI is a federally funded research and development center sponsored by
the U.S. Department of Defense and operated by Carnegie Mellon University. The
center establishes the reference model against which software development
processes are measured. CMMI(R) is registered in the U.S. Patent & Trademark
Office by Carnegie Mellon University.

    Raytheon Company (NYSE: RTN), with 2003 sales of $18.1 billion, is an
industry leader in defense and government electronics, space, information

    technology, technical services and business and special mission aircraft.
With headquarters in Waltham, Mass., Raytheon employs 78,000 people worldwide.
