Systems Engineering Seminar

MBSE in the DoD

Presented by:
Philomena Zimmerman, Deputy Director for Engineering Tools and Environments
Dr. Tyesia Alexander, Sr. Program Manager at Engility Corporation

Tuesday, May 12, 2015, 1:00 pm
Building 3 Auditorium


In this presentation and open discussion, an overview of the DoD's efforts in Digital Engineering will be presented, centered around the work in Digital System Model and Digital Thread. Included in the discussion will be the motivation of DoD to move in this direction, including the value of reusing information across systems and domains, and how the contractor community is pushing/pulling digital engagement with DoD. Collaboration efforts with USAF, NASA, and examples of use of digital artifacts will be identified, along with challenges, issues identified but not tackled, etc.

Ms. Philomena Zimmerman is currently the Deputy Director for Engineering Tools and Environments, within ODASD (SE). She leads the effort to advance the use of model-based techniques to advance SE concepts in acquisition. As a member of the SE staff, she is responsible for establishing the effective use of modeling and simulation, as a systems engineering tool to support acquisition programs, as well as the related efforts in Engineered Resilient Systems, Modular Open Systems Architectures, intellectual property, and data rights. Her team supports updates to policy, guidance, and participates in program support activities that are conducted on behalf of DASD (SE). She is also the lead for the Acquisition Modeling and Simulation Working Group, coordinating among the Services and Joint Community on traditional modeling and simulation challenges and products for support to the acquisition community.

Previously, Ms. Zimmerman served in various leadership positions within the Army’s Future Combat System Program, and PEO Integration. She served as the Associate Director for M&S, Analysis, and System of Systems Engineering and Integration. She held various positions in the modeling and simulation, test, and product development communities, including activities in radar processing, signal analysis, and use, development, and support to M&S. She has been active in standards development, and is a strong proponent of Model Based Engineering. She has worked as a contractor, and as a government civilian for the USN and USA.

She participates in various professional activities, including INCOSE, and NDIA. She has received numerous awards from both OSD and the Army. She has a BS in Mathematics from St. John Fisher College, with an emphasis in Computer Science from Rochester Institute in Technology. She is DAWIA Level 3 certified in T&E, and SPRDE.
