"David Hetherington is a leading Model-Based Systems Engineering(MBSE) consultant serving multiple defense and commercial industrysectors. He has extensive personal experience in designing and leadingdesign teams for both software and hardware covering an unusuallybroad range of system types. These complex systems have varied fromreal-time control, to software internationalization, to offshore oil drillships, to enterprise software applications, to automotive radar chipsets, to electronic publishing, and more. In addition to MBSE, he has astrong concentration of domain knowledge in safety, reliability, maintainability, and diagnostics. He uses this broad domain knowledge incombination with his MBSE skills to assist clients at two levels: - Individual Skills - He teaches engineers across a wide varietyof disciplines to sharpen their systems thinking and producehigher quality work products by using MBSE tools and techniquesto clarify the requirements and objectives of their specializeddesigns.- Organizational Transformation - He supports executives faced with the challenge of bringingteams with legacy, siloed, ""document-centric"" development habits into the integrated digital engineeringfuture.David is an active member of: - INCOSE - International Council on Systems Engineering- IEEE - Institute of Electrical and Electronics Engineers- SAE - Society of Automotive Engineers- United States Naval InstituteDavid speaks Japanese and German fluently as well as some Chinese and Spanish. He lives in Austin, Texas. automotive, aerospace/defense, medical, and embedded systemsprojects. During his long career in model-based development, Olivier has had the opportunity to work for several of the companiesthat have produced top model-based development tools. This experiencehas given him a nuanced understanding of the strengths and weaknessesof each tool, as well as a strong understanding of where usersrun into difficulties understanding the tools and the modeling languages.He spends much of his time teaching the top SysML tools as well asteaching the Arcadia method and the open source Capella tool that supportsit. He also coaches clients in developing their in-house tool methodologies, creates animated training materials, and serves as a mentor to senior product architects. He drawson his deep model-based development experience to help clients develop language and tools best practicesall the way through the systems engineering ""V"" cycle - from the initial concept to field deployment anddisposal.Olivier is a frequent conference speaker and serves clients worldwide - Europe, North America, Asia, andAustralia. He lives near Paris. Frank holds a degree in communications engineering, as well as a master'sdegree in electronics design. He worked for many years in the developmentof embedded real-time systems, gaining crucial intuitionabout the issues that drive the architecture and design of systems products.In 2001, he joined I-Logix, which was co-founded by David Harel, the inventor of the UML state charts. I-Logix was the initial developerof the Rhapsody product, a Model-Driven Development (MDD) solution.Rhapsody rapidly became the industry-leading Model-Driven Developmentenvironment for Systems and Software Engineering.Rhapsody was the spark that ignited Frank's passion for Model-BasedSystems and Software Engineering. Since then, Frank has become anexpert in the intricate details of the UML and SysML standards. He hasalso been an enthusiastic and passionate Rhapsody user, trainer, andcoach. Frank has supported many customers in the development andrealization of their products and systems. As a trainer, he has led severalhundred Rhapsody courses and touched the lives and careers of thousandsof engineers around the world. The positive feedback from these engineers continues to inspire Frankon his journey though the ever more complex universe of model-based engineering and the emerging digitalthread.Frank maintains a YouTube Channel called RhapsodyGuru where he regularly shares his experiences andinsights. (66)In recent years, Frank has been supporting client projects involving cross-domain hybrid environments usingRhapsody, CATIA Magic, and Sparx Enterprise Architect, as well as the open source Capella tool that supportsthe Arcadia method.Frank is committed to his family and likes to spend his free time camping all over Europe with his wife Leilaand his daughters Yamina and Myriam, without whose encouragement and patient support this book wouldnot have been possible."
