Software Engineering Institute


Raytheon began an "architecture journey" several years ago to institutionalize architecture as a formal practice throughout the company. Corporate Engineering's senior leadership defined a vision to address a set of software, systems, and enterprise architecture needs across Raytheon's multiple business areas. 

Since then, Raytheon has enhanced its architecture competencies through a variety of corporate initiatives including:

  • Establishing a corporate Architecture Review Board (ARB)
  • Establishing a company-wide, standardized architecting process
  • Definition and deployment of an architecture training program
  • Definition and deployment of an internal Raytheon Certified Architect   Program (RCAP)
  • Participation in external architect certification programs
  • Development of reference architectures
  • In-depth analyses of the latest architecture tools
  • Establishing a corporately accessible architecture repository
  • Establishing company-wide, architecture-centric Technical Interest   Groups (TIGs)
  • Collaborations with academic, industry and government organizations  

Rolf Siegers is an Engineering Fellow and Chief Architect of the Garland Engineering Center in Raytheon's Intelligence and Information Systems. He joined Raytheon in 1984 and leads the corporate Raytheon Enterprise Architecture Process (REAP) Initiative, Raytheon's standardized, company-wide architecture process. Rolf sits on Raytheon's corporate Architecture Review Board (ARB), leading and supporting a variety of architecture-related initiatives.

Rolf's program experience includes leading several multi-discipline software architecture teams for large-scale, software-intensive national and international systems since 1997. He is a certified TOGAF-8 architect (The Open Group), ATAM Evaluator (SEI), and Software Architecture Professional (SEI). He has previously presented at conferences by the US Department of Defense, Integrated Defense Architectures, The Open Group, and INCOSE. Rolf holds bachelor degrees in Computer Science and Mathematics from Huntingdon College and is a member of IEEE and INCOSE.
