About the Authors

Sanford Friedenthal is an industry leader in model-based systems engineering (MBSE) and an independent consultant. In his previous position as a Lockheed Martin Fellow, he led the corporate engineering effort to enable Model-Based Systems Development (MBSD) and other advanced practices. In this capacity, he was responsible for developing and implementing strategies to institutionalize the practice of MBSD across the company and providing direct model-based systems engineering support to multiple programs.

His experience includes the application of systems engineering throughout the system lifecycle from conceptual design through development and production on a broad range of systems. He has also been a systems engineering department manager responsible for ensuring that systems engineering is implemented on programs.

He also was a leader of the industry team that developed SysML from its inception through its adoption by the OMG. Mr. Friedenthal also led the International Council on Systems Engineering (INCOSE) MBSE Initiative, and is co-author of 'A Practical Guide to SysML'.

Christopher Oster is a Systems and Software Architect at Lockheed Martin Space Systems and an industry recognized expert in Systems Engineering and model-integration. Currently, Mr. Oster leads efforts related to next generation command and control systems and data analytics efforts. In his prior role, Mr. Oster was the Lockheed Martin Commercial Space Model-based Enterprise lead where he was responsible for ensuring the successful transition of Lockheed Martin Space portfolio to a model-based engineering methodology.

Mr. Oster's experience has focused on developing large scale, software intensive systems including data processing suites, spacecraft command and control systems and space platforms. At Lockheed Martin since 2004, Mr. Oster has held roles in software development, systems engineering, architecture, business development and R&D, and is a graduate of Lockheed Martin's Advanced Technical Leadership Development program. Mr. Oster is also an active member of the systems engineering and model-based communities, as a frequent contributor to the INCOSE MBSE initiative, a member of the INCOSE Systems 2025 Vision project and frequently lectures at universities, industry conferences and government offices about model-based systems engineering.

Prior to joining Lockheed Martin, Mr. Oster earned his M.S. and B.S. in Computer Science and Engineering from The Pennsylvania State University in State College, Pennsylvania and is currently enrolled in a graduate program in Systems Engineering at Stevens Institute of Technology.
